Adding a subtree requires (up to) 2 additional arguments (ett and if proto_item* is still going to be used), and I just thought it would be "API bloat" to add a proto_tree_add_item_with_subtree (and all of the other possible combinations). proto_item_add_subtree still has its uses ;)
Next piece of functionality that I would like to target is using proto_tree_add_bitmask a lot more as that is another reason for a lot of the subtrees (some that I left with proto_tree_add_text so I would remember that's what they're there for), and it would make the dissector code itself a lot smaller/simpler.

Thanks Michael for the big work.. :-)
