difficult to do anything now, there are a bunch of commits that would need
to be reverted.

Normally the world rebuild has been done on bayfront for the fonts split
branch. I have just rebased it on master. So indeed what is new on master
since October 7 may need rebuilding. But I tried with my home profile, and
all of the packages were available.

Also, QA says that there is above 90% availability on ci and bordeaux for
the master branch on x86_64, and about 90% on i686. Close to 100% on aarch64
on bordeaux as well. (Hm, this seems to be for the revision before the
merge. So I do not know; the numbers for the fonts split branch were similar,
however.)

So the only situation where I would see a lot of rebuilding is aarch64 for
persons who have disabled substitutes from bordeaux.

Or does this "my channel" refer to a private channel? Then indeed, the merge
was a world rebuild change; so external channels will only now start to
be built.

Indeed.  Likewise, ci.guix had been building the ‘fonts-split-outputs’
branch for a while already and was around 90% for x86_64-linux (it’s
still catching up for aarch64-linux though, but as Andreas mentioned,
bordeaux.guix was up-to-speed).
