Comment (by dd32):

 When I first heard of this, I was hopeful that we'd be able to simply use
 a lightweight emoji detection inline script, unfortunately I then realised
 that the emoji detection code is covering a bunch of edge cases, which
 adds some significant size..

 > 2. `require.js` .. (it will reduce the download size by a few KB for
 browsers that support emoji, increase it by ~15KB for browsers that
 I assume we wouldn't use `require.js`, but rather `wp-emoji.js` + a small
 amount of code to load `twemoji`, which shouldn't be too complex.. We'd
 also want it to run before DOMReady, to hopefully get `twomoji` loaded up
