I think the actual document cautions against using key 0, not subpool 0.
But maybe I'm looking at the wrong GSE document from 2019 ('Secure Engineering:
How to develop authorized code without compromising z/OS system integrity' by
Rob Scott, Rocket Software).

Well, SP0 is shared by default. Then there's that whole business of converting
SP0 to SP252.
Of course, it depends on the context. Authorized? Subtasks? Multi-user?

I just read that you should NOT use Subpool 0 for anything if possible.
Thoughts?
