So any provider of logind would have to provide the full interface of
the current interface (including future updates)?

The patch against systemd used versioned provides.  Is that still the
plan?  If so, it should probably be documented in the virtual package
list.

You can start logind without libpam-systemd, it just wouldn't know about
any session.  So it is about providing hooks to register sessions with
logind.
