Ed, Very good idea. I worked for IBM for several years, and never could get them to make this change, nor several others while I was there, hence I left for greener pastures as they say.

IIRC it was rejected by IBM. I can honestly see both sides of the argument. It got a little hot in the room after IBM rejected it. IBM was adamant about it. The suggestion I would give to you is build a STRONG business case for it and resubmit as a SHARE REQUIREMENT and see what happens. Do not forget to put costs for people to doing something like this. Just build a business case and you might get IBM to change their mind. I doubt it but it is worth a try.
