Some relevant information from IRC about this:

<slomo> wtay: what do you think about this bug
https://bugzilla.gnome.org/show_bug.cgi?id=698837 ? i'm not sure if i'm
thinking in the right direction there
<wtay> slomo, AFAIK you only know the possible CIDs after you open the device
<wtay> slomo, instead of only having a fixed number of properties, a structure
sounds better..
<slomo> wtay: maybe in combination with a message to tell the app about all
possible CIDs or something like that?
<wtay> slomo, yes, and a getter to get a structure with the current properties
and values
<wtay> I don't know.. we don't really do those dynamic properties anywhere like
that yet
<wtay> slomo, what we do a lot is keep the property around and set it later
when we can
