Not that I recall. Do you mean:

- checking for used C++ stdlib, which was recently implemented, or
- additional checks to be run on files installed by ports after destroot
  (which was a former GSoC project and currently lives in a branch)

How is that different from a port stating that it depends on another
port, which we already record? We don't currently check that in
rev-upgrade, but you need a force-flag to get into a situation where
that is broken anyway, so I don't see a huge need to second-guess users
that specified -f.
