> You can apply CSS to it too.

I read that as “you can apply CSS to a <noscript> tag”, which is false. Stuff within it, sure. But the <noscript> tag itself vanishes during document parsing.

I maintain my position: <noscript> is nowhere near as useful as it first appears, and should seldom be used.

I would even suggest that, excluding spiders, user agents that don’t run some or all JavaScript will normally be due to browser extensions. This is a fairly niche area overall, and various extensions are the main factor.
