I don't understand some of these.

Why?  I'm currently doing this using STARTTLS, which also 
authenticates.  I agree that some authentication might be reasonable 
as a MUST, but I don't see any reason to tie it explicitly to AUTH.

See above.

> 4. Make 8BITMIME a MUST.

I'm not sure about this one.  I can see wanting to make clients 
simpler by giving them a guarantee that they never have to do 8->7 
bit encoding.  But they probably have to anyway to deal with legacy 
systems -- submit hasn't taken the world by storm, alas.

Also, in environments where the next hop MTA doesn't support 
8BITMIME, you've put yourself in a situation where either (a) the MDA 
has to implement encoding, or (b) you might find yourself dealing 
with a lot of bounces, which will require that the client encode, 
bringing us right back to the previous paragraph.

Perhaps it's too early to be arguing the details....
