Traitor customization and armor parts

Now that we know that in multiplayer classes on the traitor side are locked to specific legions, doesn't this also kinda hint at the fact we won't be getting different armor parts for either loyalists (Mk7, Mk3 ect.) or traitors (World Eater helmet for assault etc.)? If they had this feature already planned they wouldn't have locked the classes and we already could swap the differend helmets for the traitor legions. What's your opinion?
