Not necessarily structural changes as a direct result of usage (but maybe), but I can easily see social changes resulting in structural changes via greater evolutionary success being passed down, as you note in your next sentence. This stuff is extremely complicated, we only have a rough idea of how it all works, and much of what we "know" is actually just theory.
> What's that social, or perhaps functional, advantage?
I would put my money on the notion that they promote things such as greater "wisdom" and behavioral strategies (via thoughtful meditation while normal neurological filters are reduced) resulting in more peaceful and successful coexistence between people.

Functionally more or less the same thing I would say.
