That's not what I'm talking about - security flaws in the product are probably inevitable.
I'm talking about a set of processes where rclone contributors are encouraged to adopt practices that will tend to protect the integrity of rclone's repo itself. 2FA on all new access, for example. Proper controls on who can perform sensitive operations on the repo itself, and some process to allow them to be verifiable and even auditable if need be. And so on.
I can provide my bona fides for being able to do this, and able to be trusted to. I will send contact info.
