I'm not sure I follow. You don't need a "bulky machine" to run a web application inside of an electron shell. They're pretty quick. Sure they use more memory and have a slower start-up time but it's not that bad. I run VSCode on a base level MacBook Air from at least 5 years ago (I think it was the 2nd generation?). My previous PC laptop that was about 8 years old also ran VSCode fine.
My point is that some aspects of it, typically ones you do once or a small amount of times, are the points in which it is slow. The performance after those points isn't bad and I've never seen laggy or sluggish scrolling or text input (or at least I hadn't noticed it).
