I've been thinking about this one for a while and I don't have a strong opinion as such as to
whether we should have one. But I do have strong feelings about
why we should or shouldn't.
@Nako:
Whilst I
technically agree with you from what I've heard of omegaverse stuff in western fan-fiction (and I know some of the premise conventions have stuff that does woobly-third-gender stuff for girls, too, not just the guys), I personally have not seen a single omegaverse
manga, on this site, that is not BL. (It's possible I've missed something). And both the origins and the major following is still strongly associated with BL, to my knowledge, even in the west? But, to be fair, I'm sure someone can dig up some straight omegaverse manga if they're sufficiently determined. Surely there should be some yuri somewhere there too.
Yet I must say male-pregnancy
is generally a BL thing. I may not think of m-preg when I think of yaoi, but the converse is true: I definitely think of BL when m-preg is mentioned. I can't think of many exceptions that aren't played-for-laughs. (I'm sure there's a niche following somewhere, but...)
....Honestly, pretty much all the m-preg I've seen in yaoi is either omegaverse or beast-men stuff, for whatever reason. I don't know what that's about. Anyway.
Having said that! None of the demographic-associations with these things
should pose any issue for this site, which, y'know, made a tag for "monster girls". Or so I would have thought... (Or, if the argument is something mumbled about things that are mostly sub-genres—as a previous poster said, the "villainess" tag belies that).
If I'm being quite honest, the genre-based reasoning feels just a tiny bit to me like, "most
guys won't run in to the need for this tag, so no". With fancy reasoning thrown on top. (Do note, for good or ill on my part, I am known to be vocally dubious about how un-awarely bro-culture a good portion of the site, and frequently the admins too, are sometimes.) But I may be being unfair this time.
Anyway.
The one reasonable argument for
not having the tag, given the context of existing tags, from where I'm sitting, is that there aren't
that many omegaverse manga (merely scores of them of at most)
Yet, given how fiercely polarizing omegaverse stuff is (it's pretty much either "yes! yes! yes! more please!" or "no! no! no! ew no!"), I'd want to give it a much higher priority than some other niche-ish tags.... (And, it has some other things going for it, such as it's
very well-defined...) On the other hand we don't, for instance, have
most fetish tags (vore, etc), which would I suppose have somewhat the same argument for them... ugh.
Having said all that, I, personally, happen to want
less tags on this site, or a cleaner tagging system where stuff like this is in the equivalent of mangadex's "categories". (The "genre/theme" separation we have right now is not remotely equivalent, especially given what's in each one, and how they're presented...)
...But whatever I feel about that, in the context of what has been given tags already, the standard applied here seems inconsistent. The argument for having an Omegaverse tag—after reaching some threshold of number of manga pertaining to it, whatever that is—seems quite sound.
Right now, authors and publishers are cashing in on the Omegaverse trend so it's pretty obvious which ones are not from the cover, title, and/or summary. Like, they really hammer it down that it's Omegaverse. MU would be sufficient if you really want to look for it while filtering it won't take a few seconds of checking said cover, title, and/or summary.
This doesn't quite hold water to my experience in a couple ways; as someone who reads yaoi and
doesn't really want to read omegaverse (for reasons), I've been blindsided at least three times. I've tried to add "Note: Omegaverse" to the summary when that happens, which is a workable workaround—but that doesn't encourage new series to be thus-adorned.
(To be clear, I've got nothing against people liking omegaverse stuff, and it has at most just been an annoyance for me, "okay, nevermind, I guess I'm not reading this one". I'm just saying.)

Finally, my not-serious proposal for how we could handle it in the meantime: Make a blank series with no chapters called "Omegaverse", and just series-associate it as "shared universe" with every omegaverse series. :'p
