It helps detecting supply chain attacks. The "make dist" archive is basically impossible to reproduce, so we need to trust the uploader that it was not modified. For the git tarball, all changes are visible in the commit history. While someone still needs to look, it's much easier to spot something. And that is not theoretical: The xz backdoor did just that with a modified build-to-host.m4. > This just makes packaging harder. I'm not sure what you mean with that.
