Thanks for that!

Partly. As Björn already said, the svgz file extension still is 
mentioned in a way that could be understood to say that the gzipped 
variant *is* the same mime type.

I think we have now agree that it is not, right?

One way to address this would be to mention it elsewhere, stating this 
is just a convention, and how it needs to be handled. I do believe that 
the registration template is not the best place for it, though (maybe a 
WG Note that establishes the filename convention and shows how to serve 
that stuff over HTTP?).

Of course an alternative is to make it a *separate* media type. I 
believe that Maciej Stachowiak said at the Lyon TPAC that Safari on 
MacOS internally uses media types, and that they actually had to add a 
workaround so that they could map both *.svg and *.svgz to the same 
(hopefully I got that right; cc'ing him). That's exactly the kind of 
problem I'm hoping to avoid.

Best regards, Julian
