I definitely agree with your point in general, but your first three examples, ATHENA, the mask, and the gattling gun fire rate were all bugs or at least inconsistent with the rest of the game from my perspective and should have been fixed. Though, I can see the humor in calling them "features".

That being said, it would be great if Bethesda fixed other, more annoying bugs with such gusto. For example, the social menu is still bizarrely inconsistent to use and the Friendly Fire perk is so inconsistently implemented it might as well not even exist and those two aren't even major bugs that are still around like the fast travel bug or Ward's impetuous "behavior".
