I've pulled this, but I do have a request (or two, really)..

The octopus merges look cool, but they have the problem that if there
are subtle bugs introduced by interactions between branches, they are
a pain to bisect. So in general, I advise people to avoid them.

But the *real* thing I note is that merges are more subtle than normal
commits in the first place, and octopus merges are subtler still - and
your have no explanation at all outside of the 'merge X Y and Z into
ABC'.

Please write more of a commit message explaining what those branches
*are* that you are merging.

Which is the second part of the request: when you ask me to merge "the
following branches", the branch names are basically line noise. I'm
not in the least interested in seeing what the date of a branch is.
That adds no value.

So can you please instead describe the branches by what they do than
by some internal branch name you used. I made up my own "names" for
the sub-branches in the merge message, but it would be much nicer if
you did it in the pull request.

So, for example, I changed "rcu-exp.23.07.2025" to be "Expedited grace
period", which seems to be what that branch name was cryptically
trying to say.
