Sounds like a good topic for this mailing list to me :)

We need it in the same way we need per seat LightDM configuration (for
things like configuring one seat to do XDMCP). It seems likely to me that
there will be display manager specific methods that are inappropriate to
put into a general purpose seat manager like logind/ConsoleKit.
SwitchToGuest () is the main one at the moment.

For most applications, using logind / ConsoleKit should probably be
sufficient. I think contacting the display manager directly is nicer than
accessing logind for most graphical applications as it better maps to the
information graphical apps need (i.e. don't care about text terminals). I
never pushed for other DMs to adopt it like I had originally planned, so
not sure how many apps will consume the interface.

There's always been the option for us to flesh it out to be a full seat /
device manager. I don't see any demand for such a feature (i.e. logind is
working well enough for that) so I have no plans of doing that.

In summary, no change from what it is today unless anyone has some clever
ideas.
