One thing that could be done by somebody who knows the standard /really/ well, is a proper SVG sanitizer/conformity enforcer. SVG is powerful, even in its basic abilities, but all of the projects I've seen so far have no guarantees of security or safe parsing. Its probably too niche currently, probably only really useful for things like Mediawiki. But, I think having the ability for users to upload .svg's like normal images onto sites would catch on pretty quick.
