The line-based format has had the flag since v4.4 (issue #286), where it prepends -p to the built-in getty, which turns it into login -p and passes the environment on. The block format was written from the three documented tty variants and the flags listed in the tty documentation, and passenv was in neither, so it was left out. Converting a tty line that used it therefore lost it, with nothing said. It only reaches the built-in getty. An external getty is handed its arguments through command, so there is nowhere to put a -p, and the setting is refused with a warning rather than quietly ignored.
