Here, the Ubuntu developers roll out in-house universe security patches (additional backports of new patches against historical versions of the packages), which was previously not available
I’m not sure every package should be considered supported in LTS, so this not being available by default looks ok for me
You do, but not when your distro is EoL and not with livepatching to avoid reboots.
Not true. 22.04 is not EoL and it doesn’t get all CVE patches backported unless you’re on Pro.
Huh, that was hidden deeper than I like. https://ubuntu.com/security/cves/about#security
