I tried Googling for the problem you refer to, but couldn't find
anything. Do you have a link or example of a baseline problem in OBJECT?

I'm not sure this is usual anymore, with the proliferation of content
management and blogging software.

While I think we can certainly improve even installed UAs to send more
helpful Accept headers, but it may be overambitious to assume we can
change /all/ installed UAs to stop mindlessly sending */*. So without a
HTTP 1.2 to differentiate old from new style requests that would be
problematic. (I suppose alternatively we could actually use a completely
new header like Accept-For-Rendering or something.)

Sorry, Mikko, I'm still not clear what you mean by "supports". And would
you mind elaborating on how such a user interface might work and what it
might look like in practice (from the end-user's perspective I mean)?
