Looking at the circuit of the Qume drive, it is certainly not designed to work with disks
with both holes, I can only imagine that drives only expected disks to be one or the other
when it was designed, but it could easily be modified with a three position On-Off-On
switch to disable either index sensor, or to have both working as usual...

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.
