future changes but never upgrade it and completely avoid the problem. It's
a small price to pay for being able to relax retesting after rebuilding in
the future.
That's my preference but I have yet to be associated with a company that
does it that way.

Yup. That's what I do. There is a slight downside to this approach
though. Speaking of which, does anyone know of a reliable source for
8", hard sectored floppy disk drives? ;)~
8" double or single density? :D (not that the drive mattered, was just
a controller thing of course).
I never had them two-sided, though. Had (borrowed) two Bulgarian
clones
of some I believe Shugart drives (not sure really). They worked
reasonably
well - with my disk controller hard & firmware, used to run MDOS09...
Single side double density was the maximum MDOS could think of (and
had
to be tricked into seeing the 256 byte sectors as 128 byte ones).
And - lo and behold - many of these disks are still alive and can
run, MDOS09 being emulated in a DPS window on a power (PPC)
machine (including my then written graphics editor which has made
many PCBs, was usable years before anything of comparable usablity
would become usable for the PC world).
The 8" disks (which later became 5" and then 3.4", _partitioned_ to
use all of the 1.44M, ROFL) are files now.
