You've been invited to riecointeam, probably the more that have access the less chance it ends up locked up when someone leaves. Clo1, myself, and (invited) riecoin/gatra are the current owners but you should be able to commit PR and open new repos (let me know if you run into any issues).

Personally I don't find much need to call something "official"... The only official Riecoin anything I recognize is the longest valid chain on the consensus rules that I've agreed to, currently that's Riecoin 10.2 (soon to be 0.16.3 authored by clo1 if miners agree to those tightened consensus rules). My personal bar for valid consensus rules are those that would be vetted by the community then supported by miners.
