I had the same idea: a lightweight variant of Electron, that just uses WKWebView for the GUI and JavaScriptCore for the core functionality, passing messages between them (serializing via JSON). I have a proof of concept already, but it's not cross-platform so that's a major downside, and I don't think many people need the combination of (1) Mac-only, (2) lightweight, (3) using JS for the core logic, (4) using web views for the GUI. I just don't think there's a market for that.
