Likely true. However, remember that a PDSE cannot be shared except within a
single SYSPLEX. If you try to share it across multiple SYSPLEXes or MONOPLEXes,
then "results are undefined" and likely to be terrible (corrupted PDSEs).

Use LLA. It can be used to buffer any load library, not just the LINKLIST.
./ ADD NAME=CSVLLAnn
LIBRARIES(-LNKLST-,
NPHPN.PGM.LOADLIB,
DCHPN.ENDEVOR.EZTPLUS.LOADLIB)
FREEZE(-LNKLST-,
NPHPN.PGM.LOADLIB,
DCHPN.ENDEVOR.EZTPLUS.LOADLIB)
./ENDUP
is an example.

I can't help with this one.
