SCF allows for three things:
- Reference counting which is better then the alternative new/delete memory
allocation system.
- Interface based programming.
- Plugin system and the ability to call C++ functions in other plugins.
Communication to COM and CORBA is not the reason. We don't do that
(anymore).
The most important reason for SCF is (in my view) the plugin system. That is
very important in CS.
