I’ve wanted to use a variety of SVG filters like this at times, but the problem is that their appearance varies significantly from engine to engine and by scaling factor, and so it only ends up working for subtle things where imprecisions don’t matter much, and I end up regretfully but consistently going back to raster stuff. Also the pixel-by-pixel nature of them means that things like feDisplacementMap destroy antialiasing, which spoils half of the situations you might like to use it.
