My point was not about SMTP smuggling, but about potentially revealing DISCARD rules to the outside world (since they cause later rules to be skipped entirely). Eg. a discarded sender receives OK on any RCPT TO, whereas an allowed sender sees usual recipient/relay restrictions.
This has always been the case with DISCARD tactics and is part of the canonical argument against using DISCARD: it gives senders false indications of success, such that innocent (false positive) bystanders get no clue of any trouble.
