It does "make source" so it only triggers a download if the file is
not already in the cache. And typically dead upstream servers are used
to host dead projects, which don't see releases very often, and
therefore we likely already have the tarball in our cache.

True, but it's also generating a lot of noise.

To be honest, I am not 100% sure my proposal is the best solution, but
if we're aiming to reduce the number of build failures, dropping false
positives is important.
