Create class in package?

This may be an awfully silly question - by why can't I directly create a
class in a (not-yet-existing) package?

Maybe I'm missing something, but what is the point of forcing me to
create the package hierarchy first (admittedly, a one-step operation),
and only then the class itself?

Wouldn't it be much more convenient if the alt-ins new class dialog
would accept a fully-qualified classname & create the necessary packages?
