Good. That's when they were first marked 'theoretically obsolete', at
least. Now, when did they _actually_ become obsolete, and why?

I didn't ask who; I knew that. I asked you _why_. Admittedly, I happen
to know that too - but I want to know if _you_ know it.
Since you've taken it upon yourself to decide the timescale of the
removal, surely it's reasonable to expect that you do actually know what
you're removing and why it's obsolescent?

That's also an insufficient answer. Why now? What are the factors you
weighed up in favour of removal, and against it? I assume you gave it
some serious consideration?

Even if the chip drivers in question really been unavailable for that
period of time, rather than merely hidden behind an extra config option
-- people with embedded systems are often slow to update. That isn't
really sufficient reason for removing those map drivers rather than
taking the obvious alternative solution. You do know enough about the
code you're changing to know what that alternative solution is, right?
