Not at all. The assembler can check in a DCB open exit and report on the
mismatch.
That burden shouldn't be placed on every utility, language processor,
or program. Simply, the check should be coded in OPEN, and any attempt
to modify the attributes of a nonempty existing data set should ABEND.
Similar considerations should apply to inadvertent overwriting of
PDS directories.
