I am sure that would totally depend on your enviroment and how you wanted to structure your security. We also give that authority to QSYSOPR and each of our MIS staff. That said, we are a small shop with only three MIS people.
At minimium, I would make sure you have two accounts with full authority, because if a profile was to get corrupt or disabled, you wouldn’t want to not have a seperate way to get into it.
I would do the same thing with SST profiles. We only had one once upon a time, and it’s password was either lost or the account locked (can’t remember which) and that was a nightmare of a problem.
