Sounds like a good idea.

The difficulty is that we need both the Git URL and a commit ID.  Is the
commit ID available?

If we have all of that ‘guix import elpa’ could just extract that data
and generate the right thing.  For packages that don’t have a URL/commit
associated with them, it could just keep doing the same as now.

WDYT?  Would you or Carlo like to give it a try?  :-)

Thanks,
Ludo’.
