That'd be nice, but I'd even settle for the plain pdf attached to the email.
Unencrypted sensitive data in an email is a really bad idea. I hope they never do that. Although what I would really like, and think is long overdue, is an extension to email that normalises encryption and sender verification. It's ridiculous that email can be spoofed like that. (The same is even more true for phone numbers.)
I have a laundry list of other issues I'd like fixed in email, but I'd be happy just to get end to end encryption and sender verification.
