The problem with this is it leaves me checking if I can render every single
glyph before I can write it, which means I have to do it in javascript, and
makes SVG much less of a mark-up lanaguage, and more of a javascript drawing
API [*]  for example if I get a fragment of SVG, I'll first need to parse
out the text and the fonts, then test etc.

That is more of a problem certainly.

Jim.

[*] I know I generally use it as such, but that's beside the point.
