I take as more an obvious observation than a statement of direction and have not seen anything in kind from Communications Server. TCP/IP has been made the strategic direction by customers for some time. Like most we have been steadily moving away from SNA especially SNA hardware 3746 FEPs are almost gone as applications are migrated to Enterprise Extender or updated to use web services or MQ connections. RACF provided support for TCP/IP links for RRSF previously only APPC. The war if there ever was one is over and TCP/IP won. SNA specific skills are short supply.
VTAM won't go away but some things like IBM support for 3746/3745 are going away. IBM has announced end-of-service dates for Japan, Europe and the Middle East, but has not yet announced end-of-service for the Americas and parts of Asia. IBM has a good history of providing compatibility and a migration path for applications I expect they will continue to do so. That is one of the z values.
