As this is still a proposal ...
It would be handy to have an update handler on a collection. To update collections to be used in, for example, prop_search in blender 2.7 one would probably use the scene_update handler as the CollectionProperty doesn't have an update handler.
Moreover we can add handlers into bpy.data collections.

I do see the use case, as in some other renderers you get direct visual impressions. But mimicking this in cycles/compo is not the place imho.
