Huge depends on what you have available for DASD at the time. If most of
your volumes are allocated, and there is little room for anything new, 2
3390 Mod 3s to hold the HFS (now probably ZFS) could be huge. At my last
contract job, we just got a new Shark when I started, and at that time there
was triple the amount of DASD space. They decided to flash everything as a
test, which gave me a GREAT test sysplex - all dasd was copied and totally
separate from the production sysplex. Every time they asked me to allocate
another 5 Mod 9s for something, there was plenty of room.
Contrast that to my last full time job where in 1996 they still had lots of
real 3380s and 3390s in their newly built datacenter. The dasd to hold
double the amount of data just to hold an order wasn't available. Of
course, neither was ShopZ back then, but a lot of smaller shops are still in
that kind of situation. DASD is a lot cheaper now, but adding more still
costs real money that many shops are unwilling to spend.

Yes, the HFS used for electronic delivery needs to be double or triple the
size of the package being downloaded. Your characterization of this HFS
as
being "huge" and "a problem" are what I would disagree with. I just
downloaded z/OS 1.10 plus four XML FMIDs, and it all fit in one zFS
(appropriately sized). I don't think that HFS was "huge".
