Here on our departmental mailer, we reject a moderate number of mails
which present that broken header, but (strangely?) I don't recall
anyone complaining about it. So the mails can't have been very
important :-)
Our ACL snippet reads:
deny !verify = header_syntax
message = Your message headers contain invalid syntax: $acl_verify_message\n\
[etc...]
and yes, I think you need smtp_return_error_details = true in order
to make that work; at least we did set it true, with a comment that is
citing

*However*, I have to admit that the above "deny" is preceded by an
"accept senders = ..." with a shortlist of senders whose MTAs were
fundamentally broken but it was politically expedient to us to accept
their mail. As best I can recall, none of them were for the
"Undisclosed recipients" thing, however.
all the best
