It seems to me that that would make coding somewhat more difficult.
You'd have stuff like the following all over the place:
UInt32 dummy;
if (canAcceptNULL) // Initialized earlier.
exists = FtrGet (creator, number, NULL) == errNone;
else
exists = FtrGet (creator, number, &dummy) == errNone;
That's a lot messier than:
UInt32 dummy;
exists = FtrGet (creator, number, &dummy) == errNone;
