Scanning your comments, I haven't learned about what tracking is accomplished by serving the https://cdn·ampproject·org/v0·js file itself, can you please comment on what data (if any) is collected by being 'the' place all AMP sites phone home to on page load by default?

Two other points, and I hope these are received as constructive criticism.

1- You only score 'B' on SSL labs for the domain serving the AMP JS file.[0] Maybe this is intentional so as to include support for Android devices that no longer get updates but it's not great security for the rest of us.

2- Your page explaining the project executes Google Analytics tracking code and has no privacy policy and does not disclose the fact that you are tracking visits. This is a breach of your very own Google Analytics T&C's[1] which read in part "...You must post a Privacy Policy and that Privacy Policy must provide notice of Your use of cookies that are used to collect data. You must disclose the use of Google Analytics, and how it collects and processes data...".

Neither of these inspire confidence and I hope you can get at least one of them corrected soon.
