but that's just being completely wrong headed, there's nothing special
about the xmlhttp request that prevents degradability, my over 2 year
old example showed a page which used xmlhttp to update without reload,
yet degraded perfectly, it was a trivial example of course, but I've
done more complicated stuff - I realise since Safari and GMail have
come out with this, loads of people have jumped on the technology so
maybe it's immature to some despite that actual longevity.

but that's rubbish, there is functionality - it's what the javascript
provides etc.  It's wrong to say there's none, you may feel there's
nothing that can be usefully done as fallback, but that still means
the page itself should degrade to something - not just error etc.
