Thomas,
To be precise, there is a "conformance level" for static SVG, not a 
"profile" for static SVG. The SVG family of specifications doesn't describe 
details for conformance levels as deeply as it does for profiles. For 
example, the static SVG conformance level is described with a couple of 
sentences, whereas the SVG Tiny 1.2 profile has its own lengthy 
specification. Perhaps there should be one or two new profiles. (But 
profiles are a lot of work. Don't hold your breadth.)

I sort of disagree and sort of agree with Antoine. Unlike what Antoine 
says, I believe there is clearly a use-case for SVG as a replacement for 
placed static graphics (i.e., EPS replacement), but in the direction of 
Antoine's comments, there is also a use-case for SVG for placed animated 
graphics (i.e., animated GIF replacement), and a third category would be 
interactive, animated graphics (i.e., replacement for animated GIF with 
image maps), and a fourth category would be a web application (where you 
add arbitrary scripting). And that's just four use-cases among many.
