This confused me a lot as I first assumed you are talking about
System Integrity Protection... :-)

These files would no longer be properly attributed to the port in the
registry, so they might be left behind on uninstall.

It sounds like you need the deactivate hack that is already in use for
some ports that needed to replace files:
https://trac.macports.org/wiki/PortfileRecipes#deactivatehack

I would deactivate all ports known to install files there in a
pre-activate phase in the main sip port.
