I actually thought that the module version had already been bumped for 4.8. At
least this is claimed at http://gcc.gnu.org/wiki/GFortran#GCC4.8.

However, I just had a look into module.c in 4.7 and trunk, and both show:

#define MOD_VERSION "9"

I'm confused ...

Ah, yes.

Huh, I'm not really sure if we really need the interface for the case of an
ABSTRACT or unlimited polymorphic type (I'd rather think that we don't).

But if you have a case where this makes trouble, it should surely be fixed.
Otherwise: If it ain't broke, don't try to fix fix it ... ;)
