My recommendation is simple: do password caching things at the
(single) place closest to a human user, or do nothing (just trust
ssh-agent/gpg-agent).  Otherwise the user will have to track down the
code between the UI and ssh/gpg to make sure where his secret is
really cached.

If Tramp had been designed to be mainly used by other programs rather
than human users, it might have caused the deficiencies.  However, I
believe it's not.  i.e. Tramp is an *application* rather than a
*library*.

Yes, password.el is a library itself.  But no one will be confused
about what it does.
