but in case you actually tried to do your homework first ... well i'm
failing to find the old mails myself. something is rather b0rked with
the mail archive indexing; google and duckduckgo produce mostly hits to
the mbox files.

no, it's not.
the reason is that the huge CI delay makes it impractical to know
whether a change will still land in time for branch creation. also,
people just don't pay attention to the branching announcements in real
so the alternatives to soft branching are a) restricting the source
branch before branching (which is obviously counterproductive) or b)
accepting the need for a significant number of cherry-picks (which are a
hassle to make, and an annoyance in the resulting git history).

yes, and that's entirely fine. the whole *point* of the process is to
make it irrelevant when it happens. if you rely on the time of the
downmerge but are not a release manager, you're doing it wrong.

but if you wanted to get rid of the direct pushes, the forward merge bot
(which is rather automated at that point, unlike back in the day) could
be easily extended to push and stage the downmerges as well.
