People here go from circle jerking to panic mode very fast. I don't see the problem

It all depends on what Evan meant by that statement. I think we can all agree that no enforcement is very very problematic. Miners do not necessarily have to be sympathetic to DRK. Additionally, no enforcement would open up an attack vector on the Masternode network. Someone who doesn't like DRK can simply mine at a 20% advantage to everyone else, while undermining the system that lets DRK function.
There has to be enforcement. I suppose the advantage of the RC3 voting method is that is has been tried and tested so in that regards surely less risky to turn on?
Let's wait to hear from the captain..
The RC4 system has inherent issues that were documented in Jira, plus it also has a systematic risk to the network (Sporking is less risky than a hard fork, but there's a risk the network forks wouldn't actually go away when the spork was turned off after a failure). These few issues combined with the fact that we've reached 80-90% payment efficiency tells me that it's not worth the risk to the network to move from the RC3 payment system.
Also, I have a separate plan I've been considering as an alternative that carries no risk and can be done at RC5's launch. Basically, I would set a minimum protocol version and boot anyone not running RC4 or later off the network. This should get us to 98%+ payments.
