I would just let the administrator configure this, without debconf.
You might also look at what systemd does: start the supervisor for users
on login (and stop on logout), and allow users to request the supervisor
to be started at boot (and kept after logout) and give administrators
options to allow/deny such requests.

That seems unhelpful on any installation that doesn't just have up to
five local users, but use an LDAP directory with thousands of users.

This is probably also a bad idea if many users exist.
