Question for @tunetheweb.com for @perfnow.nl, can you detect if the 'prerender until script' is supported and fallback to prefetch if not yet supported

The aim is to automatically prefetch in that case. Not implemented that yet though. We'll see whether that makes it for launch. So for now if you have both prefetch and prerender until script rules then it will do both (but only make one network request since it's clever enough to dedupe).

Ideally other browsers also fall back from prerender to prefetch too, if they don't implement prerender.

Thanks, this gives me an idea on how to add this to Hyvä but I will keep a lookout on the blog article and play around with it first before adding it.
