The only good reason I can think of, is to tell users that (and how) they
need to provide a source archive manually.

But there's a better way to do that. Just add something like this to the
PKGBUILD:

DLAGENTS+=('file::/usr/bin/sh -c echo\ '"$(printf "%q" "Could not find %u.
" \
           "Download it from $url, and symlink it to $(pwd)/.")"'\;\ exit\
1')

source=("file://something.tar.gz")

Besides not suffering from the problem that Ido describes, this approach
has the advantage that users can install a custom file:// dlagent in
/etc/makepkg.conf if they want, for example one that automatically searches
for such sources in ~/downloads and symlinks them into the PKGBUILD dir if
found:

DLAGENTS=(...
          'file::/usr/bin/sh -c find\ \$HOME/downloads\ -name\ \$(echo\ %u\
\|\ cut\ -c\ 7-)\ -exec\ ln\ -s\ \\\{\\\}\ %o\ \\\;\ -quit' )
