This is also how alpine does it, looks like this in the APKBUILD:

https://gitlab.alpinelinux.org/alpine/aports/-/blob/8a6b5840955a28cc5c24f4c806865aba01c6e684/community/vaultwarden/APKBUILD#L12

Maybe makepkg should warn instead of fail when attempting to build for an architecture that's not in $arch. This would be less complicated than implementing "all" with exclusions. It would also make it easier to consume the often poorly-maintained packages of the AUR.

With this, $arch remains useful for test/build/release automation to decide which arches to build for, and to check whether the package is arch-independent.

Maybe arch-independent packages should even be using "arch=any" instead of "arch=(any)" to emphasize that "arch" can't contain any other elements.
