Three armor stand variants

I suggest adding three variants of the armor stand that would be available in both Java Edition and Bedrock Edition. The first variant would be the regular armor stand without arms. The second variant would be an armor stand with arms, which would allow players to place swords, tools, shields, and other items in its hands. Armor stands with arms already exist in Java Edition, but they require commands to obtain in normal gameplay, so it would be useful to make this variant available in survival. The third variant would be a horse armor stand, which could be used to display horse armor and a saddle. These stands would be useful for decorating builds, stables, museums, and displaying equipment. All three variants should be available in both editions of the game.
