Well, I've got one up on ya.  I've been doing this for a few
YEARS.

Believe it or not, I've seen DSHD diskettes WITH hub rings.  In
fact, I have a few in my collection.

I guess a reason that HD diskettes have no hub ring is so then
the dumb-ass user can tell the difference between a "360K" disk
and a "1.2M" disk just by looking at it.

I've seen DSDD diskettes without hub rings, but those are a PAIN
to find.  I wouldn't waste my time worrying about those silly hub
rings.  Just get DSDD diskettes and get it the hell over with...
