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 non-system libraries are PDSE. The only thing that is "weird" about them, to me, is that a PDSE can contain either executable programs, or non-executable "data". The reason may be in the documentation somewhere, but I have not run across it. The main delay on my systems at system start up time is long after NIP is complete. But even on my _old_ z9BC, from IPL until I can logon to TSO is less than 5 minutes. There also seems to be a large amount of "wistfulness" to eliminate ECKD disk architecture.
