They didn't deal with it at all. It didn't work. No normal 8-inch
floppy disks have both index holes in the jacket. If you convert a
disk from SS to DS, or vice versa, by punching the other index hole
in the jacket, you have to cover the original, unless you're going
to use it in a drive that has only one index sensor (typically an SS
drive).

I've got at least three boxes of NOS Dysan disks with both of those
index holes present, so they certainly were made commercially.

Yup. I've got similar NOS ones also.
Since those are not "normal", or at least uncommon, please send one such
disk to Eric for his collection of odd stuff.
It would have made sense for a drive with both sensors to have jumpers,
that could, if needed often, be wired to a switch.
When I repunched 8" disks, I put a write-enable tab over the old hole.
Never having seen anything like this myself, I would be interested in
how the box is labeled!!
