Well, yes, I hardcap my 28 MSU capable z9 and 16 MSU to save software costs. I have no JAVA production workload. The current crop of JAVA infrastructure for support (CA-CSM, z/OSMF) do not run well :) And any argument to increase the cap, with the resulting increase in z/OS, Cobol, CICS charges is not going to be well received.
