> proprietary format

I also used CorelDraw for many years before moving on to Inkscape, and there were definitely some features that I still miss (e.g. better power clip behavior, blend shapes, etc). But I have came to appreciate Inkscape using SVGs because it allowed me to build my own tooling around it, I only needed libraries that can read and write XML.

SVG is maybe not the best format and Inkscape has many extensions that made their SVGs nonstandard (e.g. mesh gradient), but it is a fairly accessible format. I am not sure the gains promised by a proprietary format would be worth losing out on various SVG/XML tools.
