The only thing you lose, and I am not sure it's necessarily a loss, is
fallback methods.
Scenario: brltty is configured to use polkit+keyfile for
authentication.  In this scenario, polkit support was built, so we won't
hit the bug I reported yesterday.  The polkit method descriptor
initializes just fine.  But for whatever reason, polkit authentication
doesn't work on the user's system.  We could still fall back to keyfile.
