Based on something out of band of the document, the mime-type being
the least cost, even if it's not perfect, new headers and educating
configuring proxies etc. would be preferable, and could solve the even
worse issue of application/xml text/xml that Mozilla supposedly

Not a lot, and wacking it onto the image/svg+xml registration wouldn't
take much effort at all, updating servers sure, that's a bit of
effort, but only people authoring SVG applications need do that.

So Batik, KSVG etc. will become basically useless after Adobe release an RCC 
capable UA until the kind open source developers find the time to implement 

The Use case is simple, getting content to users, if the users UA doesn't 
manage RCC, I need to have that UA degrade, switch may get us there, but it's 
an awful lot of data being shipped, for all the clients.  Shipping 200k of 
RCC'd SVG to TinyLine at 10USD a MB is pretty nasty given that all it'll get at 
best at the end is 5k of static SVG image that it could deal with - In reality 
it's likely to get nothing it can render at all.

Nope, I feel it's a rather complicated goal, and would much rather deal with it 
outside of the document.
