However, the current situation is this: more than 60 boards (all of
them ARM, it seems) use very different settings:

Until all these are fixed, it indeed makes sense to work around issues
cause by such incorrect settings.

As usual, this being a 1.3.x release, I haven't even compiled this
kernel yet. So if it works, you should be doubly impressed.
