This is a very long term plan.  There will be no changes of this sort in the immediate future.  When the changes are made, there will be a very clear migration path.  Since the ways in which the context can be used are legion, I am not sure if there will be a completely backwards compatible API layer, but this will be the goal for as long as possible.

When the time comes to make this change, there will be an opportunity for more discussion (it won't just be mentioned in passing on IRC and then done willy nilly).  I'd welcome any ideas or proposals anyone has now, but I doubt I'll have time to participate in any discussion that happens in the foreseeable future.
