Yeah, I was running 2.2.x prior to my upgrade and never encountered
this.

Ah I see:

When a message is received with the SMTPUTF8 request, Postfix will
deliver the message to a non-SMTPUTF8 SMTP or LMTP server ONLY if:

* No message header value contains UTF-8.
* The envelope sender address contains no UTF-8,
* No envelope recipient address for that specific SMTP/LMTP delivery transaction contains UTF-8.

I wonder if this will break a lot.
