Imagine how much extra work would have to be do e to accommodate unconventional body types like something big or small or weird like a centaur or something that could fly like an aarakocra. I'm not saying they shouldn't try, that would be a very interesting game with a lot of replay value, but 99% of devs just aren't skilled enough to do that plus as >>713933710 shows most people just play human or human adjacent races anyway so why bother? Also, goblin sex.
