Applied.

Note that git-subtree squash commits aren't git-am/cherry-pick friendly,
so b4 shazam (which applies via git-am) fails on them. I applied this
with a fast-forward merge instead, then removed b4's empty cover-letter
commit via a parent re-graft (no replay):

    git replace --graft be128920 a81b1843 a2ce139b
    git filter-branch --force -- a81b1843..main
    git replace -d be128920

That said, there is git-subrepo [1], a third-party git wrapper that
may avoid these issues more conveniently. Unlike git-submodule (core)
and git-subtree (shipped in git's contrib/), git-subrepo is a separate
project not distributed with git.
