In my opinion it's overkill. Years ago I sent inordinate time trying to protect things like this. Educate your users and encourage them to be productive. Show them the advantage of using ALTLIB. If they free SYSPROC/SYSEXEC and then can't function, close the problem as a user error. They'll catch on quickly.
