I think we agree on the prudence of professional engineers.
The definition of 'professional' is up for debate, but I'd encourage people to weigh in on the following (to IEEE, not me):
- an appropriate engineering education background (ABET/EAC)[1]
- at least four years of engineering experience in your field and under the supervision of qualified engineers
- passed two exams (the Fundamentals of Engineering [FE] exam, which is now a computer-based test available essentially year round, and the eight-hour PE exam)
- kept current by as a minimum meeting your state's continuing education requirements.
The sysadmin role has traditionally been a focus in that environment (e.g. controlling access to cluster resources).
