I have no idea, but squid as far back as in Alpinelinux v3.13 depend on squid-lang-es, I haven't found any obvious why yet.

because the depends trace based on symlinks in the package. there's a bunch of language packs, for /usr/share/squid/errors, and one of the symlinks is spq -> es in that folder. the languages are split into packs, and that symlink is in the main package, but the es spanish translations folder is in -lang-es.. so the tracing makes the main package depend on the spanish language pack to satisfy the tracing
