To me, it would make more sense to pull out
the descriptions rather than add extra identifiers.

This might be tricky to implement.  Maybe each config
backend could also be responsible for loading these
extra pieces of information.  That way each distro can
easily change defaults as well as descriptions if they
choose.  Dbus etc would then also have access to this
information.

Then if you need extra information for your particular
backend you can include it in your data.
