> Most of enterprise development is on rich web apps that couldn't work at all with javascript.

Doesn't enterprise development stay within enterprises? As for the public facing web, even if the functionality requires Javascript, having it look like crap without Javascript does seem kind of lazy. I'm even for being lazy, I don't test everything and on every device, but when something is pointed out to me, at least I realize it's suboptimal, and don't rationalize regression into progress.

Nothing really changed to make these best practices moot.
