I mean githyanki is from a non-PHB source, however that they implemented it as Githyanki, and not Gith with Githyanki and Githzerai subraces, lead me to think this was purely because there are githyanki themes in the story so its the exception. I'd like to think SCAG content is added for obvious reasons.
I imagine when it comes to monsters rather than player options, it'll be more of a whatever fits.
