We've certainly felt upgrade pain — we've used Ember since before it was called »Ember«. Also, we're a 1 person tech team (myself) at a small startup.
However, I like the current rapid pace! I think both the frequency and the magnitude of changes are good. JS changes really fast, it's important that Ember keeps up (which I think it does thus far).
Also, I think the core team does a good job making upgrades easy! Sure, during 0.x upgrades were excruciating at times. But that's to be expected with beta releases. So, we're pleased with how things work and I think the core team does a great job!
(I'm not saying that people who disagree are necessarily wrong, circumstances differ. Only that this hasn't been a major issue for us since 1.0)
