It adds potential depth by adding to the metagame on top of DOA's already deep mechanics. Not having meter, doesn't make your game shallow however.

I'm also referring to the discussions about making normal holds locked behind meter. If they did do that it would have added depth? Its not necessary but just add them in anyway? Its just weird how no other game goes around asking for a meter based system and SC hated locking its GI behind meter. I've played 2D for years and I just don't see why DOA people have a fascination for meter=depth/complexity.
