RedHat Bugzilla does contain bug reports from users of dnf on Centos 7 and RedHat employees did work on them.Also looking forward to CentOS 7 -> AlmaLinux 8 in-place upgrade support, after all Elevate already supports it without Plesk being in the above indicated that work would be in progress on this feature this year, but you've indicated that we should all just wait until EOL of CentOS 7 in 2024.on the other hand, there are also arguments for the thesis that it is supported and maybe that support is just well not documented and updated (in a typical open source project way 🙄)?

There are multiple arguments for the thesis that it is not supported:
