Well, as I said before, those rewrite rules do only exist because of
some broken AUR handlers (sorry, dude :p ) relying on the current
location of the files we currently provide. The next release
announcement will contain some notice that hardcoding the source tarball
URL is discouraged and unsupported. We might eventually remove the
rewrite rules although there is no schedule yet. This is just a favour
to all AUR helper developers :)
