The goal of this patch is to kernel code that never gets executed. It
removes a load of completely dead code. It is the only thing that this
commit does. Why do you think this is "going into wrong direction" if it
only removes dead code and refines the documentation up to date?

After the dead code has been removed it makes sense to propose a better
mechanism. Maybe the one that you are speaking about. But you need to
remove the cruft first.
