Controlled versus immediate.

Been suggested that I replace using
ENDSBS *ALL *IMMED
with
ENDSBS *ALL *CNTRLD DELAY(120)
That I can understand because of the .0005% of programmers who actually
use the shutdown op code or check for that particular status when doing an
i/o or something.

It was also suggested that I change
PWRDWNSYS OPTION(*IMMED) RESTART(*YES *FULL) IPLSRC(B)
to
PWRDWNSYS OPTION(*CNTRLD) DELAY(120) RESTART(*YES *FULL) IPLSRC(B)
If I've already done the ENDSBS, and waited for the appropriate message in
QSYSOPR, that what's the benefit?
