Haiku's icon format[0] seems to solve this issue: not only it supports per-shape level of detail, allowing elements of an icon to be hidden, appear or replaced based on the icon scale size, it is also much smaller than SVG (supposedly average size for Haiku icons is 500-700 bytes) so it can be used directly.
