please reply to reviews individually instead of replying in the cover
letter.

It would have made it easier to review if the new tests were added in a
separate commit.

I dunno, I feel like that's not quite useful. If we didn't want to take
the broader cleanup we'd instead apply v1 of your seires. In this
version of the patch series it's plain unnecessary churn because we
remove the code anyway.

This information is quite curious, as it makes me wonder why it is even
noteworthy to point out. My basic assumption is that folks who send a
series to the mailing list test their stuff, so there is no need to
explicitly say so.

I mean I of course know why this is here: it's the typical "let's check
all the boxes" output that AI is so happy to generate. *sigh*
