Suppose I have this 16 bytes zoned number: f9f9f9f9f9f9f9f9f9f9f9f9f9f9f9xx. Converting it to packed bcd will give 999999999999999x.

AFAICT from the description of the instruction the last byte of a zoned number contains *both* a sign nibble *and* the least significant digit of the number. So zoned format can represent 16 digits + sign. But IIRC you changed this in v2, so maybe you realised that already.
