Fully agreed.

Thats why the libzypp-bindings are currently moving away from being
generated automatically to a clearly defined API. It is a bit more
work upfront but provides a couple of advantages like

- dramatically reducing the size of the generated bindings
  (because almost all C++ type conversions can be dropped)
- hiding the libzypp internals
  (who cares for 'zypp.ZYppFactory_instance().getZYpp()' ?)
- make the API fit natural into the target language
- backwards compatibility
  (provide the same binding package across multiple versions
   of libzypp)
   
This is work-in-progress, see zypp-devel for details.
