You suspect correctly.  The need/approach has come the library and
associated worlds, but it is clearly applicable in a wider context.

A library has a collection of books, a museum has a collection of
artefacts, etc.   However a farmer could have a collection of animals

By making Collection a subclass of CreativeWork it does imply that the
creation of a collection would be a conscious creative act by a creating

However the parts of a collection would not always be creative works
themselves (fossils in a museum, toys and books in a children's library,
etc.) hense the need for isPart to be added to Thing.

I have equal aversion to diving down such deep dark rabbit holes!

Would we not avoid that by indicating that a Thing can be part of many
collections or none, a Collection can contain zero or any parts that may
or may not be in other Collections - or am I being naive? ;-)
