Great! I've deployed the fix on the "master branch", so you should get
it by default the next time you pull and reconfigure.

You might get a warning from `guix pull` about "downgrades" the next
time you pull, since the wip-fix-53329 branch forked off the main
branch... not sure. Anyways, it's safe to use --allow-downgrades this
time, if necessary. Check here for a reference on the subject:
