Suppose a coin (could be Monero, or could be something else) requires 20 confirmations everywhere (exchanges, merchants, whatever). Suppose this coin also had an update that refused to accept alternate chains deeper than 19 blocks ago. That would, in theory, kill the 51% issue, right? What would the downsides be?
