I don't see where this change was merged into the REL1_22 branch. So is this a question for master instead of the release?

It was merged before the release, ergo it's included in it. You can click "Included in" on gerrit to see all branches that include a change.

I don't know where it was merged into REL1_22, maybe the REL1_22 was created after it was merged, but I can assure you it's implemented in 1.22.

Changing summary anyway, since backport to stable is sufficient to track the merge in 1.22

I would be inclined to revert the change, or at least make the old behavior the default (by adding a new setting that defaults to false).

Assuming that the PHP binary that $wgPhpCli points to can actually run MediaWiki (in the absence of an installer check), and also not logging failures (how can you with background execution?), is unacceptable.

This was all redone a second time in https://gerrit.wikimedia.org/r/#/c/113038/ with one more follow up in https://gerrit.wikimedia.org/r/#/c/116058/ to shore up some edge cases.

Redone? And we only have three lines in release notes? https://gerrit.wikimedia.org/r/#/c/113038/15/RELEASE-NOTES-1.23
The 1.22 changes required about a screenful of release notes published on the wiki after the fact, I'm quite sure that won't be enough. Should those changes be backported, so that people don't also have to redo their adjustments and fixes and will have to meet only one new job queue system if they upgrade straight from 1.21- to 1.22.x?

Change 132190 had a related patch set uploaded by MarkAHershberger:
Add release notes for JobQueue changes in 1.22.

Removing target milestone that was in the past.

If you want this in a specific release, have a good reason AND you are willing to find resources to fix this bug, feel free to change it to something appropriate.
