The goal, as I understood it, is to promote the practice of upstream
developers (project maintainers, release managers, whomever) signing
their code so that downstream users and packagers can verify that the
source they receive is identical to what upstream wants to put out.
For me, trusting the "generate an archive" to a third party is in
opposition of promoting good practice. I don't care if GitHub is good
today, they may not be good tomorrow, and if an upstream gets cozy to
the idea of "just download the GitHub archive" to sign off a release,
they open themselves up to a world of hurt when GitHub (or anyone
successfully pulling off a MITM attack -- unlikely with HTTPS, but not
entirely impossible) starts messing with those archives,
inserting/changing things not supposed to be there.
I do believe there is a healthy amount of uncertainty and doubt to take
here. It's great that GitHub generates archives today that are
identical to git-archive's own files. It may not always be the case.

The wiki also skimmed over exactly how to do this. "diff -r", comparing
checksums from git-archive, diffoscope?

I stopped reading after the prior point, but thanks for accusing me of
plagiarism when their example doesn't even take the same route I did.
Or accusing me of having it untested. I use the command all the time.
(And if you're saying any upstream developer doesn't understand what a
tag is, I'm sorry. It's irresponsible to not know how to use your own
tooling. Learn git and get good at it.)
