Suppose the case the goal is to load a member of an archive libname.a(member.o), but as in the plain case you get as input libname.so(member.o). In this case you will cut of the member producing the resulting string libname.a instead of libname.a(member.o). Should this situation also be handled or is this forbidden?

No, there is no case I'm aware of. Just theoretical thinking.
