That's strange, because Object.factory should only require TypeInfo_Class
which only indirectly iterates through all modules.
The ModuleInfos do drag in all their classes so what we currently don't get
is a module with only some of it's classes.

What OS are you using? Can you bundle up some files that reproduce this?
