The guile2.2-bytestructures dependency of guile2.2-guix is broken currently
(see https://issues.guix.gnu.org/46844), which makes my proposal somewhat annoying
to test ...

Perhaps replace (when COND STUFF) with (define _ (when COND STUFF))? That should
be ok for both guile2.2 and guile3.0.  It's not very aesthetical, but if the
alternative is putting everything below (when COND STUFF) in a let form
(leading to more indentation), perhaps that's ok.

cage, could you verify whether this patch works for you?

Greetings,
Maxime.
