Comment (by adamsilverstein):

 @gziolo Thanks for your work on this, that PR looks great and I will try
 to test it out.

 Since this merge/revert here the code has only changed slightly, in this
 PR we changed the way hooks can be added to a project via composition
 (from npm): https://github.com/WordPress/packages/pull/40.

 The hooks package now exports a `createHooks` helper:

 Hooks can thus be added to an object via composition:
  `import createHooks from '../';`
  `myObject.hooks = createHooks();`
  API functions are then be called: `myObject.hooks.addAction()`

 The current plan for core is to experiment with adding hooks for
 extensibility of media and other JavaScript components and decide how to
 expose them. For a platform like WordPress core, it probably makes the
 most sense to expose hooks as a global as the previous patch did, eg.
 `wp.hooks = createHooks();` while plugins may choose to their own
 namespace hooks, eg. `myPlugin.hooks = createHooks();`
