I remember one instance where a library change was detected (Can't 
remember which package was affected). The package was re-installed 
although the version number did not change.

But like 99% of the time packages without version bump will not be 
installed. One could argue that the version number should have been 
bumped in the other case.

I understand that conservative rebuilding is important for the official 
pkg repo.

But it would be nice to have a poudriere option to avoid rebuilds of 
ports without version bumps. If something should go horribly wrong every 
now and then, you can still fall back to the default rebuild behavior.

I think it should be possibly provided that port versions are bumped 
correctly. But maybe I'm wrong.
