In the past I was very active with Python packaging. For several years now I was hardly around as maintainer, so it does not make sense I am listed as a maintainer for these makes. Looking back, I should have removed myself as maintainer already much longer ago. Anyway, better late than never. It's been a fun ride, and I do intend to occasionally contribute to Nixpkgs, but not in the same way it once was.
