It won't break compatibility, as currently neither the method, nor the
imported sub will have the :method attribute.

As I understand Rafaels proposal, if package A inherits from B, and imports
from C, and if B has a sub "foobar" with the :method attribute, and C
exports a sub "foobar" *without* the :method attribute, A->foobar() calls
"foobar" in B, not in C (as it currently will).

If the exported sub from C has the ":method" attribute, or the "foobar"
sub in B doesn't have the ":method" attribute, A->foobar() calls "foobar"
in C.
