for me more then one chain is an assembly ( or complex)
I would leave Chain because in modeling sometimes people takes
domains from different places ( with different chain ids) and this
information might be useful.
We would leave the Chain decorator around (and the chain ID), even if
we remove the CHAIN type, if that is what you are worried about.

Does it make sense to talk about a protein which consists of more

are google hits, but not a huge number), but it was suggested that
this is a misuse of the words. It would make the atom hierarchy a
bit simpler to say a protein is a single chain and has
HierarchyType PROTEIN (and to remove the CHAIN type).
