It is, but i dunno why every other new framework pushes that, when you can do this in react with some conventions and 30 lines of node code. AFAIK ember fastboot gonna use jsdom and they are planning to release something for a long time, may be it is focus thing, or just too painful to do that using naive jsdom rendering.
No. jsdom is not the perfect solution. jsblocks is using Virtual DOM and have specific implementation to support server-side rendering which makes the framework more powerful and flexible.
