Suppose devs use to fix it and now the minimum is 10 votes or any other number you like. Then somebody gets banned, someone gets mobilized to army and someone is hit by the bus. Guess what? Lots of wanna-be-wit comments about "absolute moron devs". 2 votes is decent to be honest, but in my opinion 3 days is too little.
One way to handle this is combine those two mechanics: the quorum gets lower the more time has passed. When I was playing GitHub Nomic [1] we decided you needed one fewer player to vote for each day that had passed since the proposal was initiated.
