That's a good point. We still could use gobject properties and get the other
mentioned benefits though, we only need to NOT notify changes and document why
we don't do it. I think that's easy doable, we just need to not use
g_object_set (or variants) internally and make our setters not call
g_object_notify (which I take it is what's going on right now).
