Doesn't this imply the specialized thumbnailer must keep running in
order for the registration to be persistent?

Also I'm not entirely convinced using DBus messages for managing such
register plays too well with package management (packages installed as
root, thumbnailer running as user?) I think you'll need to provide a
directory where third parties can drop in configuration files similar
to .desktop and dbus .services etc.
