This may be off topic...
I used SMP(/e) about 35+ years ago, I used to build CICS.
I now get my z/OS from ADCD.  I download some volumes and have an IPLable
system.  I could download the DLIBs if I wanted them.
Is this the sort of direction we should be going in?  If IBM was to provide
the volumes every month/3months this might mean that people do not need to
use SMP/E unless they need a hot fix, you just download the next set of
volumes (or download the CICS volume(s), or the IMS volume(s))
I remember hearing one large customer talk about building a new system
every month with all refreshed products on it (based on CST from POK).  IPL
it, and kill the oldest system.   it meant one maintenance window a month -
not one for CICS, one for IMS,  one for z/OS etc.   They said it improved
up time, and saved a lot of sysprog time which they used for more testing.
It was a brave new world!
