Requiring each project to build their own versions of the module objects
is, pardon my bluntness, nonsensical.

Consider a library that only provides modules with inline/template
implementations. The object files produced for such modules will
be effectively empty. 

"Effectively empty" doesn't mean "necessarily empty". In other words: the existence of a binary object file is *unspecified*.
