I don't think there's a need for an amp cache with amp4email. The privacy concerns that make an amp cache necessary don't apply in the same way, only the security concerns that require a safe html subset. So an imap client could cache the amp js locally, and render dynamic content by querying the sender directly.

I could be wrong though, but I believe that works.

Doesn't it reintroduce the issues with senders detecting if their emails were read and where from by tracking requests?

I thought Gmail started caching images from emails and hosting them to prevent that.
