If we shared the AMRR implementation between the two drivers, your fixes
would apply to both.

If we keep them separate, other people will need to fix the ath() one - and
if they don't realize that there's another one in ural(), we end up with
two different implementations of the same (intended) function. To my way
of thinking, that leads to more maintainence cost in the code than the
effort would be in sharing the code in the first place.

The challenge is that it's not the same person doing the work in the two
cases, and in convincing person #1 that that extra work is beneficial to
the project as a whole.
