True, but <noscript> doesn't allow implementation of games either.
What matters is cases where fallback is possible, and where <nostyle>
would improve it.

It doesn't have to be briefly visible. Don't use onload, but an inline
script:
<div id="hideme">
<script>document.getElementById('hideme').hidden = true</script>
(in)visible content…
</div>
If your page uses DHTML a lot, and has fallback in many places, there's
nice trick for it:
<head>
<script>document.documentElement.className += " script-supported"</script>
<style>.script-supported .dhtml-fallback {display:none}</style>
