Well, it's about as clear as mud. If you look further in the z/OS Unix System Services planning manual under "Making changes to /etc" , it mentions BPXISETD / BPXISETS for "installing service or products that must write to /etc". It also mentions again says "IBM products create directories under /etc during installation, but IBM does not create files under /etc during SMP/E installation."
Yes, installing products does create directories... maybe even under /etc, but it is always a sample "mkdir" job where you supply the directory prefix (which should usually be a service directory). I looked at the etc that I always install maintenance under (for the last 12 years anyway) and I don't see any directories under /etc that didn't get there either from me or from the documented procedure to merge the CPAC /etc with your own.
