Electron has other drawbacks than performance as well.

The big one for me is that my workflow is based on vim, where you split tabs into buffers. There is no way to split a tab into windows in VSCode. Only windows into tabs, which is super dumb and annoying because related files are never shown together unless you click a bunch of tabs. Apparently the reasoning for this insane behavior is "yeah well electron is based on chromium so tough luck we can't do shit".
