Containers are a standard size and shape and can be transported in
many ways including ships, trains, and trucks, and moved from one to
the other without looking inside. Seems a like like packets, no?

It is not my impression that there are a lot of loads suitable for
containers but big enough to be be subject to fragmentation and
reassembly.
