It would also be nice for it to have some sort of sandbags or something on/around it when dug in to have a more visual indicator besides the shield on top of it which is also given by the Command Panzer IV I believe. Think of it like Hull Down, but for light vehicles.
I like to believe that would obviously be part of the implementation, but that they simply wanted to test the new charactaristics first before potentially wasting time on a dug-in animation that could still be scrapped, or it simply wasn't ready yet. Just like how the 221/223 doesn't have the correct UI picture and 5-star veterancy yet.
