At the risk of being contrary, if you look at the wider context of this fandom, it kind of is.
Tallying the numbers you've cited for all of those tags combined, you get 439 fics. This might not be peanuts in a smaller fandom, but given the sheer volume of existent fic in this fandom, and for this character specifically, you're looking at barely 3% of all Crowley-tagged fic, and less than that for all Good Omens fic in general.
Compared with the M/M tag, which makes up a whopping 77% of all Crowley-tagged fic -- 74% when filtered specifically for Crowley/Aziraphale and M/M together, that's a pretty overwhelming majority. Even if we were to subtract the entire 3% that makes up your listed tags (which in itself presumes that every single one of those fics is also tagged M/M, which it surely wouldn't be if it's exploring non-male identities), the number of fic depicting Crowley as a male character in a M/M relationship is still more than 70% of all fic tagged with his character.
To clarify my point above, and the user you replied to -- it's not that the character is one half of a juggernaut ship, it's that the character is one half of a massively popular M/M ship, depicted by an overwhelming majority of the fandom (both book and show) as a male-presenting and male-identified character.
And to echo a couple of other commenters above, it doesn't seem -- at least to me -- to be in the spirit of a femslash exchange to include a character, even if they may qualify on a word-of-god technicality, that has such an enormous wealth of existing material (so much so that it is effectively unavoidable if you're searching the fandom) that hinges directly on his identity as a male character within a M/M ship.
It's his inescapable tie to maleness within fandom spaces that makes his inclusion here uncomfortable, not his presence as one half of a popular ship.
