The same sort of things people wait on for other migrations or implementing enhancements. Sometimes it takes a compelling reason to change and / or go through a migration. Many people still live by the credo "if it ain't broken, don't fix it". In my client's case, I talked to the RACF team about it years ago because of the performance benefit it would have in the environment due heavy z/OS unix usage. I could just never get them to do it - but now I have ammunition since one sysplex uses bpx.default.user. So the migration is already on their plate after we finish off z/OS 1.13 migrations in a few weeks. It's been about 8 or 9 years since I looked, but I recall an issue with the number of STC userids sharing UID(0) at the time. Not a big deal, but it is something they would have to change and has to be tested. Things now may not be as bad as they were back then due to changes over the years from UID(0) in favor of various BPX.* RACF profiles like BPX.SUPERUSER and/or UNIXPRIV.
