> proved Electron-apps could have near native performance

I don't think that's true at all. Try running Zed or Sublime.

Also, big chunks of VSCode predated Atom. (The Monaco code editor was embedded inside IE10/11/Spartan Edge and parts of the Azure Portal and Azure Dev Ops.) Electron was the excuse to make it its own deliverable and not just only embedded inside other web projects. (Which is also why VSCode was not even a fork of Atom and easily beat Atom's performance at launch because it was already a battle hardened editor.)

> Atom was famously slow

It's your linter

And Electron apps do not have near native performance lmao Not even close. And neither does VS Code haha. Definitely slow just like Atom.

You missed the point
