You may want to look into handling the ENQs yourself and not let SVC99 do

Unless I'm missing something, I hope this facility isn't
available to nonauthorized callers.
You are correct it's not.
Still, I'm trying to imagine what even an authorized program
could usefully and safely do with a data set allocated with
no ENQ, given that absent that ENQ any other program, even
unauthorized, could make that data set, all its extents, and
its DSCBs vanish without warning.
Perhaps with a reserve on the VTOC(s)?

I use the flag in my sysres build program to allocate sysres resident
datasets on a newly created targeted empty future sysres volume. Since
I know what I'm doing and where I'm creating my new datasets I don't
worry about ENQ's.
