This forces every supply to have something which explicitly manages voltages which means that if one of the coupled supplies doesn't really care about the voltage (perhaps doesn't even have any explicit consumers) and just needs to be within a certain range of another supply then it'll end up restricting things needlessly. Saravana was trying to do some stuff with sync_state() which might be interesting here although I have concerns with that approach too: https://lore.kernel.org/lkml/20200527074057.246606-1-saravanak@xxxxxxxxxx/
