The footprint is probably about the same.  Small List.of values
do not contain arrays, and may be smaller than arrays with the
same number of elements, since they do not have a length field.
And, indeed, methods typically have a small number of parameters.

See the type java.lang.util.ImmutableCollections.List2 for an
example of an array-free data structure.
