This last bit will need some care and consideration, since such options are
liable to lead to the sort of fragmentation I'm worried about i.e. people
thinking they can turn them on outside the specialized environments and be
supported in doing so. But I think we can deal with that after this initial
transition. It should dovetail quite nicely with the "feature lifecycle"
stuff being discussed elsewhere.

Great!
