(FTR: I think his reaction was deplorable) By din of its presence on the front page of HN he has to say something, but doesn't actually want to engage in what probably would become a massive ember-bashing thread by others who were frustrated with ember, so he acknowledged receipt without giving a formal response.

It's quite simple and sufficient to say something along the lines of "You are right, we are working on this. In the mean time check out some example code here...".

(I fully agree with you and I think the guy's comment was really poor) "You are right" admits that it is not currently easy, and I don't think he wanted to say that outright.

There is nothing wrong with admitting you were wrong or admitting someone else was right. It shows maturity.
