I wanted users to be able to see both options,
both Gitea and GitHub, and apparently there's actually a thing
for that already, I can just use that! ok but how? 300 seems great, but there's no standardized way to use it.
The number, and the Location header as the
preferred choice is all that's actually standardized.
