Having two gigantic arrays that must manually be kept in sync, including ifdefs, isn't exactly robust. To make it easier to catch such issues in the future, add a BUILD_BUG_ON().

I don't think there's any way in which this can make a -stable kernel more stable!
Generally, I consider -stable in every patch I merge, so for each patch which doesn't have cc:stable, that tag is missing for a reason.
In other words, your criteria for -stable addition are different from mine.
And I think your criteria differ from those described in Documentation/process/stable-kernel-rules.rst.
So... what is your overall thinking on patch selection?
