I found some interesting stuff in the factions guide. Angmar is now friends with Dunland. Dunlendings and Rhudaur Hill-men are of the same origin. Considering that Gundabad was renamed into Northern Orcs, one can speculate, tha orcs in the North will be united under one faction. On the other hand, remnants of Angmar will be purely mannish now.
Hill-man country is lore-friendly, because it's stated, that after the fall of Angmar, there were no orcs left west of the Misties.
Also the mod team suggested to remove Angmar orcs a few years ago. Perhaps, they've finally decided to execute it in Renewed.
What do you think?
