I thought of this, but then my code is not very reusable by other
developers. Everybody else would have to change there base interface
type for all there interfaces. Not viable at all.

This is not what I meant. Just like the compiler has compiler modes, why
can't the {$interfaces corba} change the "mode" of IInterface. The name
also says it's a "generic interface type", so maybe the compiler could
that inject the following
IInterface = interface
end;
...overriding (or better, hiding) the old COM declaration of...
IInterface = IIUnkown
So then in CORBA style interfaces, the following two declarations mean
the same thing (just like they would if I used COM style interfaces)
{$interfaces corba}
...
ISubject = interface
end;
ISubject = interface(IInterface)
end;
Just like String can mean AnsiString or ShortString, based on a compiler
switch.
