Tested 量子巨斧 (and later, 量子巨剑) by looting it on live and repeatedly copying the character to the PTR until it could no longer give me new appearances. I have most appearances already. Copying this post onto other pieces as the observations are universal. Here's a rough categorization of the drops I received.

What I Received:

1. Removed by Cataclysm: Old weapons that either no longer drop at all or are .001% drop chances are again obtainable from Quantum items. Examples I received were 重型食人魔战斧, 豺狼人战斧黑色金属战斧邪鳍战斧黑铁锄
2. Ultra-rare: Received 厄运钟摆, one of the rarest items in the game. Also received 奈雷萨克，饮血者, but this was less exciting as it has an easily obtainable shared appearance.
3. Never-Obtainable IDs, Shared Appearance: Received items that have never been obtainable to players. However, they have shared appearances with other items that are obtainable. It is only the item ID itself that is a new unlock. Examples I received were 先锋斩首斧完美的德拉诺钢铁战斧鬼灵巨斧寒触斩首斧. I received roughly 10 IDs of the weapon titled 完美的德拉诺钢铁战斧 and 德拉诺钢铁战斧
4. Boring Same Appearance, Different ID: yes, the same as #3 but I want to stress that you can get "screwed" and get a very easily obtainable ID for an appearance you have. Examples are a common weapon from BFD and an axe from Lei Shen. I had these appearances already, just from different items. I also received the timewalking version ID of an axe I already had.
5. Generic New Appearance: to state the obvious for the sake of being thorough - I also received several axes that were not interesting that I was missing such as Shadowlands raid drops.
6. BMAH: I received the 凤凰王的金曦琴, which has only ever been available through the Black Market Auction House. Also received 奥金利斧
7. Tokens and Caches: I also received axes from the Pandaria Heroic Scenario Cache 英雄宝箱 and the Garrison Grandiose Armament tokens 豪华武器.
8. Events: Received 斩首利斧, which was only obtainable during the Wrath of the Lich King Scourge Invasion event. While this also applied to Arcanite Ripper, this is significant as it has not been on the BMAH.
9. One Never-Obtainable Appearance: 优衡战斧 is the standout as it is both a unique ID and the only item I received that was 1) previously never-obtainable and 2) present in the game's appearance journal.
10. Island Expeditions - Received 劫掠的法拉基削砍之刃 from the Quantum Greatsword, so island expedition drops are in the pool.
11. Vault? Dinar? - I have not gotten to the bottom of it, but imagine the good folks handling the All The Things community and addon will know the answer: I received 8 IDs of 加西斯，牢狱之刃. 4 IDs are obviously intuitive as direct drops from the raid, but the other 4 - I do not know what the 4 other IDs come from, although they do correspond to the original 4 raid appearances.

What I did NOT Receive:

1. Vendor Items: ~~I did not get any vendor items. I am missing some Shadowlands anima appearances and did not get these.~~ Yes, the preceding statement is true for my Quantum Greataxe testing. However, 量子巨剑 testing, my 2nd Quantum drop, brought two contradictions. 1) 徒弟的练武剑, a white quality sword sold in several major cities and 2) 格里恩巨刃 an anima vendor item. Strange that I received one anima vendor item but not others - but the vendor for the Kyrian Greatblade is somewhat unique compared to other vendors.
2. Quest Rewards: I never got around to getting the easily obtainable 刺痛巨斧. I did not receive this or any other quest reward. Even after 量子巨剑 testing, I have not received a single quest reward.
3. Revamped/Removed Dungeon Drops: As an easy example, 墓石战斧 was removed from the game when Scholomance was revamped - and has been introduced again with 10.1.5 with the return of Old Scholomance. I did not receive this item or any similar item in any capacity after exhausting the Quantum Greataxe token.
4. Appearances Not In the Journal: Yes, I received many never-obtainable IDs - but every appearance was present in the game's built in journal.
5. Dragonflight Items: I did not receive any Dragonflight weapon.
6. Crafted Items: I never received a crafted appearance. While I have every pre-Dragonflight crafted appearance, I do not have every crafted ID.

Other Notes
1. Challenge Modes - The character I am looting these on has completed both MoP and WoD challenge modes and while I seriously doubt the rewards are in the loot pool, I, personally, cannot conclude with objective certainty one way or the other.
2. Corrupted Ashbringer? - No. 量子巨剑 was my 2nd item to exhaust and no original Naxrammas items were in the loot pool for either the sword or greataxe.
3. 量子巨剑- Quantum Greatsword was the 2nd item I received from Deios. The only substantial deviations Sword testing informed over Greataxe testing were 1) Island Expeditions are in the loot pool and 2) Some vendors are in the loot pool.
