Firefox 3 supports native text rendering. There's a couple demos that show this (although you're out in the cold in other browsers, for now at least).
Have you played with SVG?
As for feature completeness I agree with you. The Firefox SVG team is very small and not funded by the Mozilla corporation (at least that was the case last year when I talked to one of its members) - the SVG standard, on the other hand, is HUGE.
What were your issues?
