Making IE non-compliant (or even more-compliant than before).

Can you remind me what the gain is? Do you have data on content of this 
type relying on one specific behavior?

I'll say it again: there are many things that can be done to improve 
things (for the whole HTTP space):

- clarify the spec for conforming headers, add examples

- write test cases

- identity bugs, lobby for fixing and/or supply patches

- identify common header micro syntaxes

- write reference implementations for the above

- encourage re-use of those patterns

- think about standardizing error recovery (or rule it out)

The last point in *my* point of view has the lowest priority, in 
particular as long as the implementations do not even treat *valid* 
header field values correctly.

Claiming we need to do all of this at the same time isn't constructive 
as long as the pool of people doing actual work doesn't grow.

Best regards, Julian
