See my comment below about piggy-backing with improvements to Style Guide.

So there's good news and bad news.

👍 The good news is that everyone that needs to sign a CLA (the pull request submitter and all commit authors) have done so. Everything is all good there.

😕 The bad news is that it appears that one or more commits were authored by someone other than the pull request submitter. We need to confirm that they're okay with their commits being contributed to this project. Please have them confirm that here in the pull request.

Note to project maintainer: This is a terminal state, meaning the cla/google commit status will not change from this state. It's up to you to confirm consent of the commit author(s) and merge this pull request when appropriate.

Thank you!

I dug into Style Guide which was hiding the moduleId=module.id in many examples for some reason ... and thus sending the wrong message!

Fixed that. Started adding/correcting advice, and soon had a lot of Style Guide "improvements".

I'll merge these with yours ... they overlap so much ... but keep the commits separate.
