The PDSE construct suffers from a number of problems including 8 character member names and having to emulate the PDS. This also could be the migration path for SPOOL data sets. Specialized SPOOL and PDS were good ideas on the 360 and met real needs. The Linux/Unix/Windows environments seem to have constructs that are more flexible and meet the needs well. The major area of work might be handling of DCB type attributes if that is needed to be done.
