Now that manylinux_2_28 is a reality, would it be time to start talking about the next manylinux version? Would that be manylinux_2_34, using glibc 2.34, based on a version 9 BaseOS? (maybe AlmaLinux 9?)
Currently multiple popular releases like Fedora 35 and 36 and Ubuntu 21.10 and 22.04 LTS already support glibc 2.34+. Also many rolling releases like Gentoo, Manjaro Stable and openSUSE Tumbleweed support it. Especially for Ubuntu 22.04 LTS a new manylinux image could be very useful, it’s also used a lot in CI.
