And then you would offend the proper vorcha, who would have enough of your tomfoolery. I daresay he would challenge you to fisticuffs!

Seriously though, while the vorcha no longer evolve genetically, they could still evolve culturally. Also, Shepard's unfavorable reaction to these vorcha and yahg wouldn't be all to different from Javik's reaction to seeing the primitives of his cycle running the show.
