I'm always puzzled by these kinds of retorts. It's wonderful that you've never experienced performance or resourcing issues with Electron apps. But just because you haven't, doesn't mean other people don't.

For the record, VSCode chugs like a MF on my Thinkpad running XFCE with 4gb of RAM. Meanwhile, Sublime Text flies

Sublime Text has been consistently slower for me than VSCode.

That’s simply not possible unless you mangled it with a broken extension. Sublime has its own native rendered with much, much lower latency.

I'm not talking about Electron apps but about VSCode specifically. I just cannot reproduce high RAM usage with it on any machine. Slack in comparison sucks bad for example, but reports of high memory usage for VSCode sound like fakes from non-users/haters.

You’re not looking at the right processes. The real work happens in “VS Code helper” child processes which take at least 500MB total, usually more. That memory is not sitting idle either, it means your CPU is churning a lot more, and its not nice when you realize your code editor is using 20%.
