> It would be good to have an additional implementation, which uses dense
> format, for {{UnsafeArrayData}} to reduce memory footprint. Current
> {{UnsafeArrayData}} implementation uses only a sparse format.
> It is useful for an {{UnsafeArrayData}} that is created by a method
> {{fromPrimitiveArray}}, which have no {{null}} value.
