[b]The Long Goodbye[/b] has for years been considered a Legacy Nightfall weapon, meaning it had a chance to drop alongside any other rewards (albeit at a lower Light Level and without the Origin Traits found on it’s more contemporary Featured Nightfall Weapons) when completing a Nightfall run of [b]Insight Terminus[/b]. While Nightfalls are no longer a major focus for PvE gameplay thanks to the addition of the Portal, they can still be accessed via the Vanguard node located in the World tab. This Nightfall option is presumably on a weekly rotator, so you will want to check in on it after each reset on the assumption that the [b]Insight Terminus[/b] will pop up at some point. (΄◉◞౪◟◉｀)
