I made the proposal because we were discussing I18N on the HTTP WG, and 
I recalled this IE issue I encountered several years ago. As I don't 
think that httpbis can help here, I thought that *this* actually is 
something for the HTML working group, because it mainly affects HTML UAs.

So no, my hope was that this WG actually would be interested in solving 
this problem.

Apology accepted.

All UAs already implement C-D in some way, they just differ in whether 
they also implement I18N as per RFC2231.

As far as I can tell, FF and Opera do, Webkit may in the future (?), IE 
doesn't. What's worse, there isn't a single format IE will grok that 
works across different client locals (such as Western Europe and Asia).

What I'm interested in is making this (or something better, should it 
exist) interoperable.

So far MS has ignored RFC2231 (and yes, bugs were raised through paid 
support channels by *very* big customers). Thus I think that another RFC 
saying "you really should do this" is unlikely to have any effect.

The proposal was made in good faith, recall I was only making an ironic 
comment once you claimed that this isn't something the WG should care about.
