Regarding this topic, I can confirm that Ubuntu intends to provide
official support for a sched_ext kernel in the 24.10 release.

We still have to finalize all the specific details of the plan, but
essentially, there will be a separate "derivative" kernel featuring
sched_ext, alongside a user-space scx package(s) for the schedulers and
tools (which, ideally, we would also like to upstream into Debian).
