The loader when in node land does nothing, can we teach it to put link/script tags in the DOM?

[Duder-onomy]

Hey,
I am having an issue with lazy engines + fastboot resulting in a FOUC.

So far, I have nailed it down to 2 issues,

1. This code from ember engines will always return true in fastboot... not sure how to fix that one. Ember engines router extension will never load lazy engine files during fastboot ember-engines#564
2. Ember Asset Loader does nothing in node land/fastboot. So even if we were to fix that first bit, ember asset loader would not load the async engines css and js anyways.

I propose we teach each loader how to load itself in the browser and in node land.
In node land, it would just append a script/link tag to the dom.
