Definitely.

There's a cascading effect. Some functions with multiple non-nil return
values rely on other functions's declared boolean result to construct their
own. So I think functions that can only return a boolean are not
"overspecified" by saying so. YMMV.

FWIW, I don't consider making a function return what its docstring says "a
cosmetic change".
