That's true, but it'd still mean you have to update all the time, and
perhaps then we'll find out it'd be easier to break the API, etc.?

OTOH, supporting (on both sides) channel contexts doesn't seem so hard
- perhaps something like
 * add chanctx
 * remove chanctx
 * change chanctx config

as hwsim commands, and then we can pretend to add/remove in start/stop
if we have non-chanctx-hwsim?
