I am not sure what "Labeler" is supposed to do. Anything on my part?

Hi @markonyango

Thanks for creating this PR!

There is no need to revert throwError usages in spec files and example apps because the ngrx/platform repo uses RxJS 7. Can you please take a look at this PR, and apply the same changes? It would also be good if you could split the changes from data and component-store packages into separate commits.

Am I allowed to force commit new commits into this PR overwriting this one? That would be cleaner imo then adding new commits, no?

Yes! Feel free to force update this PR.

Don't merge yet, git somehow screwed with my changes...Will clean it up immediately.

EDIT: Successfully rebased the PR. It should now resemble the commits to v15.
