I know COM interface come from the need to interact with Windows COM.
CORBA (in terms of FPC), I'm not to sure of. You also get XPCOM - also
supported by FPC, and I believe this is also a non-reference counted
interface.

As for rather using "ref counted" vs "not ref counted" to reference the
different interface types (COM and CORBA). Not even that would be a good
solution, because you can implement a COM interface that doesn't have
reference counting. Simply implement the IInterface (aka IUnknown)
methods yourself and remove the reference counting bits. :-)
