I do think that it is worth the effort.
we do point to tarball that are not hosted directly, and we do want to
detect an intrusion.

If someone hack our infra and mess with the git repo... since 100's of
people have a copy of the git repo we will notice a hack there...
but if the md5 value is not in git itself then someone that hack the
server can inject his own tarball and that would no be detected unless
someone cafefully inspect the tarball or get a md5 independently of
the original tarball...

so there is no real point of using md5 if we are not keeping the
'value' in git itself (and no the dowload integrity check _is_ not
worth it... if a download fail you usually know, and even if you do
not, that rarely result in something that you can uncompress and untar
without error
