Still "set current brightness" operation makes a lot of sense.

Yes, but userspace already knows if you are on AC power or not,
therefore it can decide what "current" means. If this is the only reason
then adding a new kernel infrastructure is overkill.

Also, doing things differently when on AC power smells like a policy
decision, and AFAIK policy handling is not wanted in the kernel.
