OK, thank you, although I'm afraid I still don't follow the rationale
behind this, except maybe for some really trivial additions which do not
require any other changes.

I was also initially having a hard time understanding what your email
means -- I found no mention of AUTOSEL in the Documentation and was
unsure whether this is already the review cycle or not. Only later I
came across this article [1] which confirmed some of my suspicions and
made things slightly clearer.

If I were to add a few words to briefly mention AUTOSEL to the
stable-kernel-rules document according to my current understanding,
would you take such patch?

Alternatively, I suggest adding some sort of brief
description/explanation to these patches as is the case for patches from
the review cycle.
