Hi Andrew,
When I have software issues, the vendor (in my 40+ year experience) will
usually ask for a list of APPLYd SYSMODs and/or certain modules'
eye-catchers.
I don't see any need for a total product replacement.
(It seems like you're comparing CD vs LTS (IBM-speak. none of my jobs
are CD.))
Regards,
David

For the same reason that it's difficult to define a maintenance level
in SMP/E, a single fix is a bit of a SMP/E myth. A single fix is
likely to pull in prereqs etc. so you get a whole lot of other changes
whether you like it or not.
With a non-SMP/E full replacement delivery, I can identify and check
out and test the exact code you're running. I can compare it with the
current released version. If it's important to change nothing other
than fixing the problem, I can make a single change to the code (or
merge a change from the current release if it's already fixed) and
build a custom release. I can test the version that will be running in
your system.
As a bonus, if code doesn't have to be delivered as separate modules
the compiler can work it's magic and give much better performance
through inlining, removing dead code etc.
