Wow, that's quite a lot.

Do I understand correctly that the hashes are relied on for security? In
other words, is it the package (containing the PKGBUILD) that's signed,
and once it's verified, it's the PKGBUILD's responsibility to check the
integrity of the files it needs?

If so, this should be fixed as soon as possible. How feasible would it
be? Could it be as simple as making a script that:

1. Finds the 'source' and 'md5sums' lines.
2. Downloads the packages and checks the md5sums.
3. Computes the SHA256sums, and adds them to the file.

If there's anything I can do to help, let me know.
