I guess what's in the back of my mind is that the password type might
someday not be just a function of the password, but require other
inputs.  That is, if we change the hook signature as proposed, then
the signature of get_password_type() also becomes part of that API.
If someday f(x) needs to become f(x,y), that becomes either more API
breakage for users of the hook, or no change at all because it's the
callers' problem.

Maybe there's no reason to believe that that will ever happen.

TBH, I'm not that hot about it either.  But I'm thinking this
is an API break we don't need.
