LGTM based on a cursory glance at the changes, the correctness of the testing, and the clean-ness of the backports.

I did a cursory check and it looks good. As regards:

May be check if that works better and quiets the complaints of the robot overlords? I am guessing `\backport` takes only a single parameter, and multiple `\backport`s can't be composed/nested.

Not sure what the right process is that is recommended here. May be @shipilev has a suggestion?
