Why do YOU need PDSE support at IPL time?
As far as I know, it makes no sense to _require_ that PDSE support be
available at IPL time.
If you have a business case, or a requirement for your code, please state it.

What I, personally, think would be neat would be some sort of R/O page

I think the reason is not to reduce system start up (IPL) time, but to
remove the PDS dependency from IPL/NIP. And perhaps even to replace the
need for PDSEs. Many people here _still_ seem to dislike them. I,
personally, don't have any problem with them. If fact, 90+% of all our

No it isn't.
It is designed to be used to ensure the root filesystem is mountable by the
