I'd hope so. I learned about their history via an actual play and they're actually really cool and impressive! I really hope that they implement Githzerai into the game as well since I actually like them more, having learned about them.
Back to the tags though, I think an issue we're running into is that as players, we don't know and I think a lot of us assume that having the Baldurian tag or the Underdark tag or whatever Githyanki have means that as far as the game is concerned, it's canon that we're from those places. After all, we're still a ranger or a fighter no matter if we choose dialogues marked with those tags. Same with racially tagged options.
