Right :-)

Sounds like a great innovation.

It sounds reasonable to me.

I like the approach of asking once, and then having a local state
synchronised with a signal.

It's likely that there is no expert here that knows more than you from
your great code reading & research - so I'd just go for it !
The only trick here is which dbus API to use for maximum cross-platform
goodness; I think the answer is either dbus-glib or raw dbus - GDBus is
not usable for dependency reasons: we have to build / run on very old
systems :-)
Otherwise - I'd say go for it ! and it's a shame (of course) that there
is (apparently) no cross-desktop standard for that stuff.
Thanks !
Michael.
