Tree-shaking and destructured require optimizations

It’d be great if:

const {normalize:normalizePath} = require('path');

…and perhaps also:

var normalizePath = require('path').normalize;

…would behave like:

import {normalize as normalizePath} from 'path';

…in that it would only bundle normalize() and anything required for it to run.

Tree-shaking has existed longer than ES modules. The first I’d heard of it was jslim.
