Kinda unrelated to the image but at the moment I'm thinking of removing some tags from most entries in honkai_(series), mainly character tags. The reason being is that having tags for each battlesuit makes things overly complicated in my opinion. Each battlesuit has its particular element which can be easily found with a generic tag, for example Sixth Serenade can be found by combining kallen_kaslana and mask, Kiana's White Comet by combining kiana_kaslana and white_bodysuit, Sakura's Flame Sakitama by combining yae_sakura and armor, you get the idea. This is why is important to add tags which highlight each battlesuit's particular elements. It would also erase the need to add battlesuit names to characters who are different from their original counterpart such as zhuge_kongming_(honkai_impact) and theresa_apocalypse, or yae_kasumi and yae_sakura. Everything previously mentioned would also include the cosplay tag of each battlesuit such as kiana_kaslana_(white_comet)_(cosplay), costume tags such as raiden_mei_(aeterba_purum), and other misc tags like tranquil_arias_(honkai_impact).
Now, there could be exceptions such as theresa_apocalypse_(luna_kindred) since she's not the same person as the original Theresa. Other exceptions are rita_rossweisse_(fallen_rosemary) (unless she has a different name), seele_(alter_ego) as Seele's other persona, and kallen_kaslana_(ritual_imayoh) who is a character from Kallen Fantasy VII. yae_sakura_(goushinnso_memento) is canonically Sakura from the Previous Era, so 'Yae' would need to be removed from her name. About Herrscher of the Void, adding both Kiana and Sirin tags and remove the battlesuit name could be a good idea. Other possesed characters could work in a similar way or vary case per case. I guess a general tag for Herrschers/Lawmen could also be added.
At the moment I'm adding battlesuit tags to their respective characters to make it easier to add clothing/appearance tags in the future. If you have any feedback feel free to reply.
Please bring something like this up in the forum before you go ahead to nuking a bunch of character tags, it's easier to follow and archive major decisions like this.
But to keep it brief, I think the removal of alt character tags would make searching specific designs much harder, forcing users to rely on two or more tags to find a specific unique outfit. Honkai isn't the only game we do this with, either.
The issue with adding a new tag for each battlesuit, costume and cosplay is that they'll just keep piling on since the game is still and will be updated for a long time. Another thing is, as previously mentioned, the battlesuit naming kinda conflicts directly with the lore: There's this character who looks exactly like Theresa Apocalypse, but is actually a completely different person, called Zhuge Kongming. However, the game doesn't differentiate between the 2 because there are in-game mechanics tied to character types/names. As result, Zhuge ended up being called 'Theresa Apocalypse' in the character selection menu, which translated to the theresa_apocalypse_(starlit_astrologos) that's currently used on images featuring that character.

Like I said, the forum is a better place for a discussion on such a decision. And also like I said, we already do this same thing with alts/skins for other games. Azur Lane being one notable example.
"Zhuge Kongming"-like problems can be discussed and fixed if necessary in a forum thread where people are actually likely to see the discourse, and without blowing up the comments page.

No way, please don't remove them. If it's in the game officially and distinct enough to have its own name, we eventually give it a tag here too. Same has been for all the Fate "craft essence", for the elsword classes, as well as other recognizable costume items.
You should start a Forum thread though, I'm sure everyone will agree to keep them, but this could be a good start to at least clean up the costume tags a bit.
