Yeah, strictly speaking, perhaps.

One thing that I refuse to believe is we will need only one more bit and
after assigning the 0x4000 bit to whatever that single purpose the index
will stay that way forever.  So we would need to reserve that bit as the
extension bit in any case.  If we do not have any extension forever, that
means any index entry with the bit set is corrupt, so erroring out would
be the right thing to do anyway ;-).
