I guess there are two observations, one is counts/s and the other some
estimate of uSv/s.   But given the weewx approach, I think it makes
sense to let the input device attempt to estimate into some standard units.

That's fair, but lots of people measure illuminance and estimate solar
irradiance, or ther other way around, and that's structurally simiar.

So there's still the best estimate you have, which is true, for various
values of "not quite right", for everything.

I think it's good if there are at least standard names so when multiple
people do this, they can share skin code.
