I'm not sure how big a deal that really is in a broad sense.

My friend circle in our old city included both Falstaffian omnivores and vegans, and we entertained often. It's not hard to ensure there's food available for folks on a more restrictive diet, and even my friends with UCI racing licenses generally ate like normal people at social events.

Mileage varies, obviously.

(I will say, however, that after having made a vegan "bolognese" once, I have no need to do so again. It was much more effort than the already time-consuming genuine article.)
