Well, we can debate all day what is or is not amusing, but I am not sure
reading the 256-byte directory blocks was a supported programming interface,
so if it had gone away I don't think anyone could have screamed "not
compatible." I find it amusing that one can read physical hardware 256-byte
blocks that are not there. But if you are not amused, that's okay too.

Why would this be amusing.
PDSE is supposed to be compatable/transparent to applications.
So, how would they do that without simulating a PDS directory?
