Noop is defined as a valueless value that can be added to the elements of a container.
That is not always true, in particular when the container is strongly typed and the type marker is omitted. In this case, there is no way to distinguish [N] from the integer 78.
For this particular reason, using noop as a way to remove data should be used with care, and is in practice not efficient because you first need to find how the container is defined (with optimized format or not).
