"Just links" is of course the potential fall back for both of these, clearly confidential emails can't be implemented with actual email, and short of something like message/external-body is unlikely to be multi-client (especially since the sender would want to control the controls on the content, not trusting the client to implement them).
It turns out, presenting the content in-line is very useful compared to requiring users to click away.
