I applaude this decision.
Why would anyone want to muddle up their nice distributed currency system, free from complex regulation from governments, and add a DNS system on top of it? How hard would that be to explain to someone's mom, who (conceivably), could be using Bitcoin in the future?
There is plenty of transaction fees to be had when bitcoin builds a larger user base. We don't need non-standard transactions to make mining worthwhile
The simpler Bitcoin stays, the better IMO.
