The great thing about the rewards system is that they serve as great bug bounties for things like that that normal people not trying to game the system would never run into.

Thanks. I agree that this a pretty neat way to reward bug bounties. Perhaps in the future, if other features may be added and consequently do not work as intended, then they may be implemented with witness set parameters so thst bounty rewards can be paid, but we wouldn't need a hardfork to adjust rate of bounty, only for the fix.
