Redirecting folks who don't have JavaScript turned on to a version of the site
that works for them.

I think you'll get more accurate results by testing what actually happens then
by reading a blog post.

They have some other solution for clickjacking when JS is enabled.  For
whatever reason, they'd rather use that than X-Frame-Options.  However, they
still want to use X-Frame-Options in the case when there's no script.

> Are they trying to balance integrations options with security concerns or what?

I don't think you or I should sit in judgement of these decisions.  The point
is only that <noscript> is a useful, widely used element that does things that
no other element can do.  Declaring it obsolete when it's not is silly and
counter productive.

> a usage example is not the same as a use case.

Usage, however, is evidence that the feature solves a problem in a useful way.

I'm tired of arguing.  Bottom line: we shouldn't declare something obsolete
that's used by a very large number of important web sites.
