Obviously your knowledge far surpasses mine.

I'm sorry but you're just unfamiliar with the process. I'd point out
that all my AUTOSEL commits go through Greg, who wrote the rules, and

The rules are there as a guideline to allow us to not take certain
patches, they're not there as a strict set of rules we must follow at
all times.
