You're correct. For normal use that is enough.
The idea behind leaving the last cylinder free is

We have reached the point in our Linux farm where some of our guests have
served their useful purpose.As such I'm going to 'reuse' their DASD for
new guests.
I'm sure I can 'reformat' (cpfmtxa) them as I did originally, but I thought
I would check on alternatives that others might have. All

Actually, mkfs doesn't write the entire volume, does it? You'd have to run
dasdfmt and then fdasd to get that effect, before running mkfs, based on how
I understand things... I've been known to be wrong, though... Occasionally.

Hasn't the recommendation for Linux guests generally been to define
cylinder zero as PERM space with a real volser, and then define MDISKS
from cylinder 1 for as many as required? That way the real volser can
change as needed by the site, but the MDISK volser label seen by the guest
can
