This is exactly the idea of -r1.1, and this (at least the check)
already works in the code snippet I had sent to the portage list:
From 1.1-r1 to 1.1-r1.1 no recompilation should happen, while e.g.
from 1.1 to 1.1-r1.1 the bump is as usual.

Package managers which do not want to implement minor revisions
could just treat -r1.1 as a "usual" revbump and recompile
unconditionally, that is, except for a slight extension of
the allowed versions (and corresponding comparison rules)
nothing would change for them (although their users would
then not benefit from the possible avoidance of some
recompilations offered perhaps by other package managers).
