A nice idea as the version changes PORTVERSION/REVISION aren't always a reliable indicator. If you're trying to tag a port build(s) as being unchanged from one build cycle to another, how will the changes to /usr/ports/Mk be tagged? We currently mtree the /usr/ports/Mk dir/subdirs so we can easily determine where we need to look if there's a problem and/or we need to revert something quickly.
