The SF 30th Anniversary Collection was released around the same time SF V was still a thing, so newer generations already have a more recent alternative to witness White Birdie
Now mind you, I didn't really care about Birdie's race swap either, and even less so when Capcom made him "fat" for SF V. Hell, they even incorporated his unhealthy eating habits into his movelist, so it's not like they decided to make Birdie fat for shits and giggles. It was in tone with his character arc in that game
