I have exactly the same concerns about the keymap patch. This all has
not been working correctly for many many years (and it was not broken
in a subtly way as far as I understand, but rather quite obvious).
Thus I do not understand why this belongs to stable release. It is not
a [recent] regression, nor secutiry bug, nor even enabling of new
hardware, that is why I myself did not mark it as stable.

I still maintain that we pick up for stable too many patches for no
clear benefit. This is similar to the patch for Atmel controllers that
was picked to stable and I asked why, as it is not clear how many
users might be affected (or if the problem the patch was solving was
purely theoretical, or only affecting hardware that is not in
circulation yet).
