To automatically track any usage of such methods, add also:

 - email a stack of any such method call to cleanup watcher
 - tag such method and count its usage out of those emails
 - after a year or so purge all untagged methods

This way image can actually be cleaned up without much angry guys out
there, also without a lot of work if cleanup is automated.
