Sorry. Slow reply here. I have no experience.
The closest I have gotten is subscribing to the debian-mentors mailing list where it is possible to ask for “sponsors(uploaders)” for your package. 
Also I would say that building SuperCollider from source it quite easy following the instructions or using this script by Mauro.
For those on Debian/Ubuntu feeling adventurous jumping distro - Arch is the one with the best bleeding edge package management. pacman -S supercollider and pacman -S sc3-plugins smack! 3.11.0-4 is installed. Thanks to David Runge the community repo maintainer/packager for SuperCollider.
