Same with me when I ran ServerPac installs - I never IPL'd using the
datasets provided by the installer such as catalogs, RACF, spool, SMF,
page, etc. I never understood IBM's reason for doing that, and also
never understood the reason for running the system validation jobs on
the vanilla system. What was much more important for us was IPLing the
new res pack on a sandbox system with our own system datasets, parms,
and usermods - and then solve any issues that may come up.
So those IBM-supplied system datasets were never used, and although I
could not delete them using the CPP dialog, I would always set them to 1
track or 1 cylinder before running the alloc job - just to save space.
It just made little sense to me to prove the vanilla system from IBM
works correctly. Of course it does, otherwise why would they send it to me?

I don't know how it would work with zOSMF, but I don't worry about the dataset
sizes of my SMPE target datasets. Because I never IPL using them.
I copy to new SYSRES, FDR and ADRDSSU dataset copies to single extents. Of
course, I rarely (maybe 5 to 5 times in 30 years) put maintenance into a
running system
