Promise Polyfill for BlueBird: with Babel 6 is this still a thing?

From what I’ve read about Babel 6 it looks like the runtime is no longer supported. Wondering if the suggested polyfill in the readme is still the correct approach?

require('babel-runtime/core-js/promise').default = require('bluebird');

If I prefer to use bluebird as my Promise implementation of choice in Node, rather than the native ES2015 implementation, is there a way to declare this without needing to add the require statement from this issue description in every file that uses Promise?

If you are using babel-plugin-transform-runtime with default configuration, that’s includes polyfill (but don’t export it to the global scope), you can just replace babel-runtime/core-js/promise

plugins: [
  new webpack.NormalModuleReplacementPlugin(/babel-runtime\/core-js\/promise/, 'bluebird')
],
