It seems most of the activity is in master now, and master has key-groups features, but my 5f680e44305ebc1e06905387976d413ae48d3f10 patch in key-groups looks like it can't be cherry-picked either because magit.el still uses the magit-commit-signoff variable, but I don't think there's a need for it now that the master has the "-s" signoff method.
Is testing of the key-groups branch still wanted, do some things still need to be merged to master from there, or what?
