Back in the Windows era... you could embed Internet Explorer as an ActiveX control in your VB6 app and interface with it, albeit very rudimentary.

Maybe, since Electron has evolved as a somewhat common standard... the major OS providers should get together and revive this idea. The OS provides, similar to say Java JRE, a base runtime of a browser and a JS interpreter with a specified set of helper APIs to use local functionality such as filesystem access, raw networking, notifications, yadda yadda, and apps just call that runtime.
