I think people have taken the whole "you're actually more agile in armor than you might think!" to the polar opposite of the original misconception at this point. I remember someone on here recently suggesting to me that Usain Bolt could potentially beat his 100M record in full plate armor because it's "not as heavy and doesn't restrict your movement as much as you'd think!" Just because it doesn't turn you into a turtle doesn't mean your speed and movement are equal to that of your unarmored self. Specifically talking about ranged weapons having skill penalties due to heavy armor, I don't think it's unexpected that heavy gauntlets would make your hands less dexterous or a full helmet would restrict your vision to some degree. Ultimately, restrictions and penalties would be in place as a form of balancing. At the moment, there is no way to build your character to wear armor "better", so every playstyle has equal access to the same degree of protectiveness. Obviously, this is a much greater benefit to playstyles that can fight away from danger, such as archers and horse archers, meaning melee playstyles don't have an inherent advantage in dealing with the higher amount of damage they are more likely to face due to how they have to play. Restricting and encouraging ranged playstyles to use lighter armor would allow TW to balance heavy armor around the realities of playing as infantry in the heat of a battle.
