Yes, it should be an alternative. In fury, we disabled it by default, and all those benchmarks doesn't enable it. Most objects are value bounded, not binary data bounded. Zero-copy won't have a big speed up too. But if the objects graph has many ByteBuffer/Tensor/DataFrame/ArrowTable, then the zero-copy will have a big leap. see python pickle5 out-of-band serialization to speed up pandas/numpy as an example
