I can see an obvious need to avoid corruption of the directory. Yet there is (or was) valid code (using BLKSIZE=256 from memory) to access a PDS directly. And wasn't IEBGENER with a dummy SYSUT1 used to repair the DSORG=PO of a PDS damaged in this way? So I think it would be difficult to make sensible changes to the access methods.
I'd suggest making sure there are checks in all the IBM utilities, as in the RFE, as a practical answer.
