My power is apparently real enough yesterday and today that it isn't
sarcasm to describe it.

Well, often that is true and using what is already there makes it an
easier and better solution too, since the stuff in the kernel is usually
pretty much best of breed.

In this particular case the impact of sticking it in userspace for
everything will depend on the speed we run the ADC at, and that will
depend on how much aggregation of the samples we need to do to get solid
results, and that will depend on the algorithm used to filter it.  So
we'll be guided about what to do by a beauty contest in power and
performance.  That's pretty non-dogmatic, right?

I don't have a problem with going against upstream any time it suits our
goals for the product, or even just gets us a solution so we can go on
(and clean it later if it can be cleaned).

But yes, if it can easily be made compatible with upstream, there's time
and it's worth the engineering, it often means we made better code as a
side effect in my experience.

That said I am working on a very dirty patch right now.
