Don't trust anyone claming to represent RCO, they are more than likely attempting to mislead you.
The only recommended replacement for RCO is Bloxstrap, created by a passionate team of developers, who I can guarantee, know what they're doing, and know as much about FFlags as I do.

Thank you to everyone who supported the RCO project, but it's time for me to get on with my life, away from the limelight and away from Roblox.
I'll see you on the other side.
