Because uh.. SVG is a -vector- format.
While it's possible to specify a very small subset of SVG which would
match OpenRaster's capabilities, it would carry the implication that
it had some relation to SVG (and hence, that it was based on a vector,
not raster, image model). AFAICS, it has only one point in common:
it's an open format for storing images of possibly non-trivial
complexity.
