Your point then is: is OK, they are working to continue support CentOS 7 (that is EOL), and CentOS 8 (that is also EOL)... and now working to CentOS 9. At this point, we can expect support to CentOS Stream 9 when he reaches the EOL date in 2027...
I think the crux of the issue is that you are likely not a native English speaker and are missing some of the nuances of what we are writing. I chose my words very carefully. CentOS Stream 8 was the initial direction CWP was going in as the CentOS 7 EOL was approaching and so they created the delayed repositories. Then AlmaLinux and Rocky Linux 8 released and proved to be viable (and indeed BETTER than CentOS Stream) and so CWP pivoted to supporting and recommending those true EL8 distributions. Indeed, AlmaLinux 8 is now their recommended current stable base OS. I never said anything about CentOS Stream 9 because to me it is a no-trick pony -- a beta quality OS that has no business being the foundation for a server -- so it is
irrelevant. True Enterprise Linux 9 releases (especially AlmaLinux 9) is what CWP is targeting and is currently in beta for. All of that do-si-do was caused by Red Hat and ate up quite a bit of time & developer resources (both for the binary compatible EL releases and CWP) until the landscape settled out to what it is today.
