My suggestions don't entail changes in server software.

The user of a pubnix or a flounder-style hosting service would likely
not be in a position to determine what server is used.  But they would
be able to create well-known files or append hash fragments to a few
links.  The idea of hash fragments for third-party links would be
especially interesting to explore, I think.

As are many features of current Gemini clients.
