Mostly, yes (“mostly” because derivations using “builtin:git-download”
will automatically be fixed once we’ve updated the ‘guix’ package, but
that only helps if you’re traveling to after September 2023 (commit

Indeed.  :-/

That’s a real bummer, but that’s the nature of software: we cannot
retroactively fix bugs.
