It's a new subsystem that has been discussed and reviewed for months
and thoroughly tested. Please refer to the cover letter under v8
linked in this thread. It's not related to power-management or
power-supply, it's its own thing but IMO the best place to put it is
under drivers/power/. And I will maintain it.

This is why they are in next! They are scheduled to go in during the
upcoming merge window. But since changes belong in multiple trees, we
need a cross-tree merge.

It's not safer at all, why would spending less time in next be safer?
