[aur-general] Support for remote sums in PKGBUILDs

Breaking away from an IRC convo from this morning; has support for remote sums been considered for pacman? It's currently possible to do this for .sig files (through the source array), but not available for simple sha/md5 hashes. This would let packagers do something like: source=("http://example.com/downloads/$pkgname-$pkgver.tar.xz") sha1sums=("http://example.com/downloads/$pkgname-$pkgver.tar.xz.sha1") (Of course, only for servers that generate a programmatically discoverable hash of some sort; but it's not actually uncommon) J.
