The only support for SVG in QML is that it will load a static SVG image (rendering it once unless you modify the Image sourceSize dynamically).

The reason for this is that SVG is far too slow on devices, at least as currently bound in Qt (it goes via QPainter, for example).

For example, an SVG consisting of just 3 ellipses is more than 10 times slower to render than painting a pixmap. We can't see that it is reasonable to trade such performance penalty for any visual appeal that SVG could bring over static pixmaps.

It seems that SVG is fine as a source image format, but not really practical on devices as the runtime format.

None that I'm aware of.
