Very few players in my experience are playing a particular race for thespian reasons because they are deeply interested in a non-human world view or exploring the viewpoint of something whose biology is fundamentally different than humanity.
Most players are playing a race primarily for the rules modifiers that race entails and only secondarily are interested in the psychology of that race if at all.
At the same time, I don't consider a race interesting enough to include as an option if they aren't so non-human that their biology makes them distinctive from humanity in some regard. As a GM that alien distinctiveness in something that is also a person, is very much what I'm interested in even if the player isn't.
