Is there any particular reason why this is accepted? (I

void foo(int = 3) {}
I guess it could be useful to ensure binary compatibility when
you expect to add the parameter later?
Of course this should be accepted. Omitting the name has nothing to do
with the API, but has to do with the fact that the implementation doesn't
use it. An implementation may be constrained by a base class or by some
duck-type requirement even though it doesn't use the parameter.
