Yes. But it's unclear what the behavior of the check should be. For `std::array`, it's clear, because one must not touch the internal element. For a user-defined type, "it depends" on how the user wants to design their struct. 

If the need comes, I envision we will need some sort of option so people can add other types on top `std::array` to be excluded from the check. But let's cross that bridge when we get there :)
