Happy to register that.

That makes perfect sense, too, but elements in eldoc-display-functions
must coexist peacefully with other elements there.  Currently, the
implementation is oblivious to the order of functions in
eldoc-display-funcions.  Maybe that could be changed, and
as such we'd have the eldoc-display-in-tooltip function happen
before in the list and say "no more functions after me".

Anyway, this is only relevant if you're thinking of integrating
your tooltip display in Emacs proper, eldoc or thereabouts.
Are you?
