This looks good, but it's a core-updates change: guix refresh -l
icu4c@69 says 12433 packages would be rebuilt.

Also, you should update all the variants which inherits this one to also
use gexp expressions, as it may cause problems otherwise.

I'm adding 'core-updates' to the title to avoid merge mistakes.

Thanks for working on it!
