Well, if this code gets into 5.16, it should still be marked as
experimental then, because I'm bound to have introduced lots of new bugs.
But hopefully these will be small easy to fix bugs, rather than the
current 'designed totally wrong from the outset' mess. So if there aren't
any problems, maybe mark as stable in 5.18?
