Fwiw these git hashes are a major pain point for packagers when they
are auto-updated at build time because when the package is kept in
git, the hash is different from the actual release hash. And when the
package is then distributed as a source package (.dsc in Debian), the
.git directory is gone, and rebuilding the .debs yields a package
that's again different.

I can see why you want that, but please make it easy to disable it for
packagers, or make it a static string.
