I think my concern was pretty obvious:
"No, why?"

Your commit msg is pointless. Says nothing. It says what you do, but it
is obvious and redundant. I see what you do from the patch diff.

What your commit msg is supposed to say, is explain why this is needed
and what problem are you solving.

This applies to all your commits, to all projects, downstream or
upstream. Repeating what the diff is doing is trivial and does not help
people to understand why this commit is there and what is the commit's
bigger impact.

So after I asked to provide rationale, you send exactly the same commit
without rationale.

And this is repeating in this entire patchset. Patch #1 only mentions
"no actual benefit", but it is discussible. It provides benefit in my
opinion and nothing in your commit msg gives arguments to support your
clause. Patch #2 does not need more explanations but it also does not
make sense in entire series - you want to drop the specific compatibles!
What's more patch #2 does not make any sense with combination of patch
#3 and it is not explained in the commit msg.

Patch #3 also brings zero explanations why you are doing it. From all
four patches, only one had some sort of explanation - patch #1.

Best regards,
Krzysztof
