Inkscape 1.4 Released

The more I learn about the SVG spec, the more I understand the rationale of some of the UI decisions inkscape made, and the more impressed I am by how they implemented advanced techniques like shape union and intersection, clipping and masking.

From the little I know about SVG, I wish there was an open source alternative to Inkscape that didn't support standard SVG but used a proprietary format instead.

Almost everything you need to create vector art, SVG doesn't support.

Multiple outlines in a single shape? No. Varying thickness in an outline? No. Rounded corners on arbitrary vertices? No. Non-destructive boolean operations? No. I'm not even sure SVG supports paragraphs.

Many of these Inkscape implements as live filters, which are saved as SVG extensions in the XML .svg file that nobody but Inkscape can properly load.

SVG is ridiculously bad as a creation format. It's a good format to export to, but as a backend and it's just insane. It's like using a single PNG file as a backend for your multi-layer 128bpp raster project.

I use Inkscape a lot but I can't help but notice that the best vector art illustration come from Affinity Designer, Corel Draw, and Adobe Illustrator. If you compare the quality of artwork made with proprietary tools to those made with Inkscape, it's very clear that Inkscape severely limits what artists can achieve. You can easily create complex illustrations in other tools that would be a nightmare to manage in Inkscape. Just compare how you clip something in Inkscape to how you do it in Affinity. It's ridiculous how different the two workflows are.

You might look into https://graphite.rs/ . MS Paint is about my digital art interface complexity limit, but I do read Graphite's blog posts and their app sounds really attractive for more serious artists

In what ways are they different from Inkscape? (My knowledge of Vector Editors is quite limited)
