Thank you!

Ah, I didn't even think to check the zziplib package.

Yeah, that looks weird indeed.

Oh, thank you for these ideas!

TeX Live packages kind of scare me a little, because they tend to be

small contributions to Guix packages soon, which should get me started
with the workflow, and help me fix such issues directly in the future.
