Missing routeWillChange & routeDidChange

[nickiaconis]

The polyfill presently lacks support for the routeWillChange and routeDidChange events. They are described here in emberjs/rfcs#95. This, at the very least, prevents ember-prefetch from removing private API monkey patches in favor of this polyfill.

Yep, this polyfill only currently provides access to methods/properties that do not require the RouteInfo objects (as that work is not yet done).

We should update the README's known limitations section to mention what we haven't implemented yet.

Hey folks 👋 is there any appetite for someone to do this work? I'm wondering if there is a plan for how you would be able to achieve this as a polyfill and if so then I might be able to take a quick look at it 😄

Seems fine to do, but at this point the value is pretty low. There are no supported Ember LTS's that don't already have these events...

[mansona]

yes that may be true, but it could help people on older versions of Ember on their upgrade path. This came up for an addon that I wanted to upgrade to the new paradigm but didn't want to break backwards compatibility.

Obviously there is limited value but I'm wondering what your opinion on the expected effort might be 🤔 I am happy to dive into this but I haven't had a look at what it would take quite yet
