When the issue surfaced years ago, Asterisk 18 wasn't even out yet. Must have been fixed quietly without backport to older versions.

It's better to never have offered Path at all than to implement it (with considerable fanfare at the time!), then break it via a mandatory and quite controversial upgrade path (chan_sip -> chan_pjsip), then obstinately refuse to fix it.
