I can't recall ever seeing such an ACCEPT recommendation from IBM,
probably because your own installation maintenance practices play such a
major role here.
The only reason for not ACCEPTing PTFs (USERMODS and APAR fixes should
typically never be accepted) is because you might need to RESTORE a PTF;
but if you have been successfully running with a PTF installed for
months, it is highly unlikely you would ever need to RESTORE it, and
even if some subsequent error HOLD was placed on the PTF, if it is not
an issue that has caused problems in your environment it is just as
likely that a resolving PTF will become available allowing you to go
forward in maintenance rather than having to back out the PTF. I have
even had a few rare cases where I have bypassed an ERROR HOLD to force
an ACCEPT of a PTF and "clean up" a zone when the nature of the error
HOLD was such that it would clearly never be an issue for us.
The most likely point at which you might actually need to do a RESTORE
would be shortly after another mass APPLY of PTF's (not just any "next
APPLY"). Failure to ACCEPT previous mass maintenance for PTFs already
running in production sometime before doing the next mass APPLY means
any RESTORE after that point is likely to also force a back out of PTFs
with which you have been successfully running for months. I would
expect this to add unnecessary risk by placing your system in
configurations further at variance from those with which IBM and others
(including your own installation) have done rigorous RSU-level testing.
