Validate result for the BPX.CF service in the zOSMF Security Configuration Assistant

Customers will get a notification "No CF levels are available for sizing calculation" if the BPX.CF service under Security configuration assistant is not defined. If there is a generic FACILITY class profile *.* defined, the validation result for BPX.CF service will show as passed. Despite that, the CF level(s) available for sizing will not appear and customers will not be able to utilize the functionality. This will become essentially necessary/needed when CFSIZER web tool will sunset in 4Q26 as customers will need to check and validate CF structure size when migrating to a higher level CFCC code. Can there be additional check/validation specific to BPX.* service?

Additionally, the comments in SYS1.SAMPLIB(IZUSPSEC) are helpful:

/* UNIX system service requires either a specific profile BPX.CF */

/* or a generic profile beginning with BPX., for example BPX.*. */

/* A completely generic profile for the FACILITY name * is not */

/* accepted. */

Could it be considered adding those instructions, for example, to Appendix A. Security structure for zOSMF in the IBM z/OS Management Facility Configuration Guide?
