I am reminded of RFC 8689, REQUIRETLS, which lets a sending mail client pass a 
flag telling the server
that the message must only be relayed over a TLS encrypted session.  My MTA 
implements it by carefully
checking the syntax and then ignoring it.  If you're going to send me mail, 
you'll have to live with whatever
I do with it.

Why would this be different?  Maybe I'm on a network with jumbo frames and big 
IP queries work well, or maybe
you think your traffic is big enough to need TCP, but you're just wrong.

R's,
John
