I don't buy this. SVG is  a standard for describing vector
graphics. As a side effect, it also defines <svg:image>
to pull in bitmaps; but this is by no means the raison d'etre
of SVG. Inclusion of an external bitmap is a low-level
function which all document markup languages define.
It would be perverse not to follow suit.

It was pointed out that separate @xscale and @yscale
attributes might be appropriate. Some would add a
"rotate" attribute.
