And PDSE might have been a good place to introduce (optional) FBA support. PDSE is really just FBA simulated on CKD simulated on FBA.
If you defined CKD as devices accepting count-field oriented commands, then you are correct. However, all disks I've looked at (not all that many), have a count field preceding the data, hidden by the firmware, so you could add an extra "overlaid on CKD" to that.
And why are member primary names still restricted to 8 characters!?
At the time, it was a critical decision leading to easier acceptance. I recall many people who had to be dragged, kicking and screaming, into using PDSEs at all. Perhaps a compromise would allow for an option on OPEN (?) to support an extension, but what business case could you make to IBM to support the change?
