And it's fair to wonder. We do "cheat" and turn off facility bits in "our copy" that relate to facilities that the customer, via MACHMIG, has asked not to be exploited for migration reasons. In practice, for those facilities it is not relevant whether the facility bit is on, because there is an operating-system-provided bit that is supposed to be checked to tell if it is OK with the OS for you to use it. IHAFACL, for example, has this comment for facility bit 129: "Even if this bit is on, do not use the VEF unless bit CVTVEF is on".
