It's really not that bad though. I pasted an (untested) patch below.
But like I said before, the difference is pretty minor so I'm okay with
either.

While this is true, I wouldn't want to build that assumption into the
code. Maybe there should be macros to map between the internal and
cfg80211 band indices.
