Most promising project for larger enterprise I discovered in 2017:

Single SPA - a Javascript Meta Framework https://github.com/CanopyTax/single-spa

>>Use multiple frameworks on the same page without refreshing the page (React, AngularJS, Angular, Ember, or whatever you're using) >>Write code using a new framework, without rewriting your existing app >>Lazy load code for improved initial load time.

Unfortunately also missing in lists like this one.
