Needed libraries added to Depends:, here are the binary debdiffs:

I would say it's the latter.  Any program linking against libaddresses
or libaddressview presumably already links with gnustep-base/gui and
the Objective-C runtime.  There are cases when the dynamic linker
loads the libraries in the wrong order which may lead to runtime
failure if loadable modules (bundles) are not linked properly.  But I
haven't seen this in practice and I'd say it's unlikely to occur on
modern systems.
