To be honest, in my ideal world, mshta, Electron and the like would be discontinued and, instead, there'd be a cross-desktop-platform HTML/CSS/JS app-runtime (_not a browser!_). This runtime should support a sensible, large subset of modern Web APIs plus a set of cross-OS and OS-specific APIs so it's easy to work with for developers. To be easy to use for users, it should be installed by default on all major consumer-facing OSes. So yeah, it's probably not gonna happen anytime soon...
