I know, but I'm asking about current practice.

No. That would mean a lot of keymapSSS. Doing it the keymap way
would require to have us, us-revert-left, us-revert-right, en-uk,
uk-revert-left, uk-revert-right, etc. I really don't like that approach,
thus the "independently of the configured keymap".

This really is a problem that is orthogonal to keymaps: I'm here talking
about _physical_ keys remapping, not remapping what is printed on them
(which is done after that).
