As a (mostly) C dev this is like bizarro world to me but I've noticed on HN and elsewhere that JS devs are very quick to move from one framework to an other, declaring a library dead if it hasn't received a significant update in mere months. I'm sure that there are plenty of JS devs out there who have fundamentally changed the way they code several times over the past few years.

With this mindset I can understand that there might be some reluctance to consider a standard library that would be "set in stone" and shape the language basically forever (and potentially create a burden of legacy feature that needs to be maintained, C++ style).

That's going to happen whether they expand the stdlib or not. Witness Array.prototype.flat() (because .flatten() would break websites using MooTools). I think the staged process they use and compilers like Babel work to get the proposed API in use so it can be evaluated against actual in-the-wild use, without contributing to ossification.

You know what they say: If it ain't broke, let's move to a brand new framework.
