@ionic/cloud-angular imports full rxjs library

As I mentioned in april in an issue, the code for the cloud service of ionic (@ionic/cloud-angular) imports the full rxjs library. The minified bundle is still about 150kb big and it is not necessary to import it completely. Is it planned to get changed soon or has my company to change to another push service provider?

The mentioned issue:

You could also fork the ionic-cloud-angular library, fix the imports and use that one.
(And then send a PR so these changes can be merged in by Ionic)

Edit: Just saw a PR already exists. So fork the library, apply the PR to your fork, use that one in your project.
