Unfortunately, changing this is not as simple.

When implementing the '-' to '@' thing, I have proposed to switch
‘package-full-name’.  While I still think it would make sense for it to
use '@', it would require a full rebuild of every package + extra care.
For example among other things the tests will not be happy for ‘guix
graph‘ IIRC, and the Guix website uses it to access Hydra links.

It would be great if you manage to solve this issue.  :)

Thanks,
