Maybe I'm misreading the code, but would an old standalone application
image, compiled for the old jumptable format, really still run on a
system with your patch applied?  Only in this case we can leave the
version unchanged.

It would not hurt, ideed.

The manager will be continually amazed that policies he took for com-
mon knowledge are totally unknown by some member of his  team.  Since
his fundamental job is to keep everybody going in the same direction,
his chief daily task will be communication, not decision-making.
