Here's the real problem. The JS tools got really powerful and the majority of users now experience faster dev cycles and richer features. Now users cannot go back. If we started serving smaller sites with less js people would complain about all the little features they liked that don't exist anymore.

A developer now has a choice: use the big framework where you can satisfy those now entitled users or give up some success and make a tiny site with limited use of js. I'm all for the free web but I know which choice I would make when running a for-profit company.
