I think the downvotes are partly because of your "Cue the downvotes" at the beginning... beyond this, even as a big fan of Electron based applications, for a lot of things, it's not a great fit for a many things. I'm not sure a vector graphics program is a good fit or not, or where the edges in performance may be. I know that using it for heavy filters on raster art would be too slow comparatively for many.
Frankly, VS Code is probably the only moderately complex application that really shows off Electron. Many electron apps just aren't that well written, and not to besmirch any developers working in other toolkits, making good JS code in a larger codebase is a different kind of skill than most are used to, beyond this, the techniques and approaches for performance gains are also fairly different.
I don't think Chrome, JS, Node or Electron are going anywhere any time soon. There are some definite value wins in that space. That doesn't make it a great fit here, but I'm happy to be surprised.
