But those are not tag tarballs though.
That being said, yes, the tarball format changed once in the past, on
purpose, so that it could actually be reproducible and allow things like
the “alternative local workflow” of https://wiki.debian.org/Creating
signed GitHub releases. I can’t remember when that happened, but per
this page that was prior to April 2016. And AFAIK, it is not subject to
change again for this exact reason. ;)
