@freakazoid "But isn't resource usage (not to mention download size) going to be high in Electron pretty much no matter what you do?"
Short answer: no, it's not. Electron does not have 'high resource usage' and never did.
"It's just that using a full-blown browser for each application"
Electron isn't a "full-blown browser" and this is very much part of the misinformation that is causing all this bullshit. Its internal complexity is not meaningfully higher than that of a modern UI toolkit, and it's not Chromium either.
