Why do you consider Electron maladapted? It has really reduced the friction to write GUIs in an enterprise environment.

I didn't really mean Electron, but rather unholy amalgam of three languages, each with 20 years of "development", which mostly consisted of doing decrapifying and piling up new (potentially crappy) stuff. Although Electron with UI context and system (backend? background?) context both running js is another can of worms.
