This came up yesterday and I wanted to capture it: I've been sitting on the name just in case (I grabbed it when it briefly seemed like we needed an "in-between" place for non-core, non-ecosystem stuff like editor-support packages).
Right now, https://github.com/perl6-contrib is just sitting there with me as the only member and nothing else (though I did freehand sketch a Camelia profile image with "P6 CO", just for fun). Anyway, it's there if the need arises; just let me know. Trey
