Some examples would be small stuff like SRL gear being unobtainable due to the record book not existing or class items not dropping from silver engrams or sidearms...
I don't know if this is possible anymore but if you could an actual final update that ties up these loose ends...
If I was bungie I'd do this if we were bringing D1 to PC that's the only way I see this happening

The last update was in 2017 so what you got you have. Also Bungie moved completely on to D2 in 2017 so there will not be a PC port. Note.. while Bungie does update the PC port of D2 they did not create it. Vicarious Visions did the original port but since Bungie left Activision they no longer have access to this studio.
