Google Docs – How to Share Only One Page of a Document

Doesn't appear to be so. Google Docs isn't a full-fledged word processor after all.

What happens when text from one page gets pushed over to the other? Do they both get new revision numbers? Is it automatic?

Did you try uploading one of your Word documents and seeing how Google Docs converted it?

You might be able to fake something up by using the footnote feature in a non-standard way. Insert a footnote at the top of the page and the text for it should appear at the bottom of that page.

Whatever way you do it you're going to have to manually update each time.

Google Docs follows the same standards as Microsoft Docs when it comes to comments in documentation; they are ephemeral only to ask/provide clarification on a paragraph/sentence.

After which the highlighted portion should be corrected and the comment removed when all collaborators have agreed on the change. In Microsoft, this will be done with deleting the comment.

Google Docs provide a semi-state where you can mark the comment as resolved

So that when you export to .doc, the comment markup will not appear there.

As shown above the first comment is not there because it was marked as resolved in Google Docs, so it makes no sense to deal with the comment again (this based on the assumption that by resolving the comment, one has resolved the issue in that comment).

Another way to do it, would be to create a copy which will not carry across the comments.
