There's a lot of redundancy and obsolete stuff in the main repo Wine package. I maintain wine-stable and I have just 45 lib32 dependencies.
To compare:
Main repo wine: https://github.com/archlinux/svntogit-community/blob/abf380b...
AUR wine-stable: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=wine-...
