Hi there!
No, you are not the only SuperCollider user - but I am neither using
GNOME nor jack. I switched to Pipewire some time ago and had my own
issues, which were solved when starting the IDE like so:
pw-jack scide
It's great to see you've managed to get it working, though!

I guess the main reason being not to dictate uncertain dependencies,
i.e. not clobbering profiles with unneeded packages (like in my case).
Enjoy and have fun,
