I'm not sure what you're referring to exactly, but you can certainly run ICSF without RACF. You can also license base z/OS (which includes ICSF) without the z/OS Security Server (which includes RACF) if you wish. I think RACF requires ICSF, or at least often could, but ICSF does not require RACF. >Accommodation to French law which (formerly?) harshly prohibits >encryption? (I suspect ROT13 is proscribed.)
