Isn't it the other way around?  Looking at the git repo, the git tag is
v12.0.0.0, not 12.0.0.0, and Guix strips version prefixes like "v", "V"
and "version-".  Also, IIUC, the current consensus is that home pages
and source git repos are separate things, even if sometimes their URL
coincides, so the URL may need to be copied into the 'url' field.

Greetings,
Maxime.
