Ah, that definitely was not clear until now.  So the handler never
needs to track those files.

I'm wondering how often the caller will be able to make use of this
(i.e. how often it will happen that two or more calls to file-local-copy
will require the same file and will know enough about each other to
coordinate the file-deletion).

Do you have some callers in mind?

Right, and this support will not be used on the handlers's side but on
the callers's side.
