I guess only the microchip people can answer this and in the event of
silence, the best course of action likely is to proceed. Maybe give it
some time? It's summer holdiday time in northern hemisphere.

Yes, sure. But this was deliberately RFC and I deliberately merged all
the removals to give you a quick idea of the dead code size. I didn't
expect this to be applied as is but rather generate a reply regarding
the purpose of the code that I propose to remove (in smaller steps).
