They probably existed, but I don't recall ever
seeing a non-bootable program disk for an Apple II. And data
disks are not much use without program disks.
You needed to use a special disk in order to not include DOS on an Apple
disk. It did free up a small bit of space. Apple's minimalist DOS was so
small it was rarely worth the effort. Program loads didn't obliterate the
resident portion of DOS.
CP/M on the other hand took significant disk and RAM space for the DOS and
command interpreter, portions of which were lost on program load and needed
to be reloaded on return to the OS.
