Read: Bringing the power of AMP to Gmail

See: A New Frontier for AMP (AMP Conf 2018)

I am opposed to AMP in general. For email, I am wildly opposed.

Aside from the whole proprietary format thing, this would allow requests for and execution of scripts as well as dynamically replacing content after sent. It also adds a fourth MIME part text/x-amp-html (in addition to text/plain, text/html and text/watch-html), and requires another codebase to extend the total file size for this progressive enhancement.

What do you think?
