I don't agree with your assertion that a new pool is a problem. Let's face it, last year kano.is was a new pool. Yes, it's very well run and maintained by one of the two guys responsible for writing the code in virtually every BTC miner available. I have nothing but respect for the work kano and -ck have done and continue to do. However, people flocking to kano.is does exactly what you're stating is the problem: centralizing the hash on a single pool. Currently it's AntPool and f2pool. Take their hash and point it at kano and you've still only got a single pool. Of course, I trust kano's pool far more than either AntPool or f2pool, but that doesn't alter the fact that just pointing a ton of hash at a single pool is dangerous. Remember when ghash.io had more than 50% of the global hash rate?
There's a huge difference between a newbie and someone like Kano and ck putting together a pool and code. Those two are able to be completely trusted due to their involvement in the community. We already trust cgminer, etc. It's not a fair comparison.
We're in no danger of kano's pool taking over the world. That's crazy talk. Antpool exists to run Bitmain's farm, and so long as it and Bitfury exist, there's plenty of balance. Kano could grow to 50 PH and we'd still have a stable distribution.
