That depends on what you think the result would be.
What do you think companies who use Electron, CEF, embedded web views, etc today would do if those technologies all died tomorrow? For example, do you think GitHub, WordPress, Figma, Discord, Whats App, Slack, Trello, Skype, or Spotify would hire native Windows desktop development teams? (Or even Mac/Linux desktop development teams?)
Personally I doubt that there would be any increase in native app development. Any developer who cares about this is already making native applications, Electron just makes web apps slightly more convenient.
