There is a problem because same symbol may be used at different positions for different packages and package may not be known or changed afterwards. I think point to mapping with attribute or embedded would or have solved it. Not all circuits end up on a circuit board and for these package pin numbers may not make any sense and better removed.

To be fair most of the time when you change the parts symbol for
something like an fpga there is no good way to make the new extra pins
fit in the space that was there.

Have you ever used a suite that supported changing packages which
actually handled it correctly more than 90% of the time? I have used a
few and the 10% when it failed drove me nuts.
