When I first go into #guix, I experimented with every little thing. Now I only change my configuration every three months or so, while for anything else I just use guix shell. And my system remains solid and predictable, with no weird state and quick environment variable tweeks building up leading to library collisions etc that can come to haunt you at a moments notice. Just my studio, as I designed it to be.
This has meant that I havent contributed much in a while. But I'm honestly not the type to try out the newest software as its released. Everything I need is packaged in guix already. And of all the things I've packaged, I never started actually using any of them lol. So I'm kind of glad I didn't submit them upstream, because im not sure if we really need to include any packages that noone is using.
