For a large non-C, existing z/OS installation, IBM compiler pricing issues in the past were always a powerful dis-incentive to add anything that required the C compiler,
When pricing was based on total system capacity, existing large installations couldn't cost-justify adding the IBM C compiler for additional $1000's per month for experimentation and would have highly displeased if any product suddenly required it. Being able to license the compiler for use only in an MSU-limited LPAR provided some relief, but still required the installation to be willing to eat the overhead of setting up and managing another LPAR just to play with C.
