 Review comment:
   Personally, I don't like this name, because "array container" means something storing the
array. Here you don't store the array, but iterates through the nested array. But I'm ok with
this name if there is no better name for the class.
   The same for `SystemViewCollectionContainerAdapter` class and `register...` methods.
