Ah, this is another "feature". That message is the default for a
temporary error, because some sysadmins do not want to give out specific
data about their systems to other hosts.
Sorry, I'd forgotten about this additional feature. You should be able
to override this by setting
smtp_return_error_details = true

The problem is that an ACL verb can have many conditions. Not all of
them refer to verification; that may be only part of the story.

No, you are not wrong[*], but this is an awkward interaction between
verification and ACLs. It's my fault. I didn't think about it hard
enough when I was inventing ACLs.
However, I am sure that changing the default would now be a bad idea,
because it would be so incompatible.

reports all 550 errors as "Unknown user", whatever the text says. :-(
