I'm fine with investigating the missing parts before or after moving to
guix-artwork.git.
For what it's worth, I vouch for moving all to gnu.org and possibly expressing the issues in the appropriate debbugs instance
Then, I might be able to collaborate in sorting out some issues
I never used Mercurial. I should learn from scratch.
Also, I can't access the issues on bitbucket because the login doesn't work in Icecat (plus some nonsense about upgrading my account and coming mobile apps that require me some voodoo right now)
