Comment (by jmroot):

 A lot of these are from `port select`, so as far as this is an issue with
 base, it's a duplicate of #43996. Any files left after uninstalling all
 ports were not recorded in the registry, and base has no way of knowing if
 such files are data that you want to keep. If some ports are creating
 unregistered files that should be deleted when they are deactivated and
 neglecting to delete them, that is an issue with those specific ports and
 individual tickets should be filed for each one.
