I think this is primarily delayed because people don't agree it's a good

I don't think this needs much further testing. We should just remove the
enable/disable knob and go ahead.

I don't see to many problems here so far. For a complex feature it's imo
already in a pretty good shape.
Some more eyes on the code would be good, given it touching lots of code
that's central for crash safety, but if not, I don't think it will block
things.
