Yes you a probably right because I sent this patch after Ludo shooed me
away when I made a PR on codeberg
(https://codeberg.org/civodul/guix/pulls/17#issuecomment-2995653).

  $ ./pre-inst-env guix refresh -l -e '(@@ (gnu packages gtk) cairo)' | wc -w
  4279

Would you like me to make a v2 and use a graft?

Cheers,
Remco
