Well, I checked again. From CERN Oct 28, 2022 Linux Future Committee meeting [1]:
- Several bugs have been encountered in Stream, which were not present in RHEL.
- Some user communities had previously expressed concerns on the feasibility of using Stream in a production setting. This feeling has also recently been expressed internally by some IT groups.
- CERN is evaluating our original recommendation [0] of utilising CentOS Stream as the default Linux Operating System.
