What was the rationale for this? Does anyone still use this philosophy?
If so, why?
There is no rationale. It was wrong then, and it's wrong now. It
kneecaps the most valuable feature of SMP/E - RESTORE! Unless, of
course, you like RESTOREing the entire FMID.
OTOH, doing ACCEPT kneecaps the possibility of a RESTORE to a point
earlier than that ACCEPT. SMP/E strikes me as a half-hearted design.
A better design would permit RESTORE to any prior service level provided
the necessary elements remain in the GLOBAL zone.
Suppose you have two suspect PTFs, A and B. In order to tentatively
RESTORE B you must ACCEPT A. If RESTORE B doesn't solve the problem
there's no posibility to RESTORE A.
I believe VMSES/E does better. It has no analogue of ACCEPT. VMFREMOV
simply re-installs needed components from the DELTA disk, the analog of
the GLOBAL zone.

There is a way to RESTORE prior to the ACCEPT. You need to BACKUP your
entire SMP/E environment, then restore it.
