If the client don't want compression, it can just refrain from initiating
a compressed session, and I'm prefectly happy giving servers a way to
announce their abilities.

Actually, it should go away, it is totally counter to the idea that
your content would depend on the other end.

if anything, replace it by a client-header that says something intelligent
about rendering abilities and area:

	Render: text, graphics=color, area=1024x768, javascript
	Render: text=color, javascript

It would obivously have to be at chunk boundaries to remain in sync.
