FWIW, I completely agree with Dan (Carpenter) here. I absolutely
dislike having these kinds of files, and with subsystems imposing weird
restrictions on style (like the quoted example, yuck).

Additionally, it would seem saner to standardize rules around when
code is expected to hit the maintainers hands for kernel releases. Both
yours and Martins deals with that, there really shouldn't be the need
to have this specified in detail per sub-system.
