You need to work with variables of type IInterface then so that the 
reference counting mechanism works correctly. The compiler does not 
generate reference managament code if you work with a variable of type 
TInterfacedObject or decendant. E.g.:

var
   i: IInterface;
begin
   i := TSomeInterfacedObjectDescendant.Create;
   (i as TSomeInterfacedObjectDescendant).SomeMethodOfThatClass;
end;

This just looks ugly...

The other possibility is to define an interface for the class you want 
to use, but that's duplication I'd like to avoid...
