Would you agree, as I've suggested, that there is no inherent technical limitation to using 223.255.255.0/24?
FWIW, I still see 'classful behavior' with WindowsXP (all recent service packs and such like) and also Solaris 2.7 (not sure about later releases, I'm guessing it's still there though).
My point here is that many years after CIDR we still get weird anomalies in IP stacks --- so I wouldn't bet on anything being safe unless well tested.

I don't doubt that there are OS's with bugs. However, my assertion is that 223.255.255.0/24 would continue to work under even Pre-CIDR gear. Therefore, even if an OS exhibited classful behaviour, that would be unrelated to the usefulness of 223.255.255.0/24. Are you saying that Class-based routers can not use 223.255.255.0/24? Aside from real design errors or unintended Features, 223.255.255.0/24 (and 192.0.0.0/24, 128.0.0.0/16, and 191.255.0.0/16) should be able to be assigned, should the IANA no longer need to maintain the reservations. That being that they are/were reserved to be assigned to some purpose, and not because they couldn't ever be used.
