I'll try to get sbot and git-ssb into the main nixpkgs tree but this will likely take some time as the PR backlog is horrendous, I hear.
I'll make a development channel, like the ssb4nix repo for ssb related projects. In it we can have scuttle-shell and patchbay, etc. which seem to be problematic to introduce just because they add many node packages, which I find only somewhat understandable. I still want to use its packaging philosophy since it would allow me to easiyly switch between versions.
