To be fair, most studios seems to still be using CentOS 7 and Rocky 8, latest Ubuntu version tend to be 20.xx, all of them relatively old from like 2020s sometime.
AFAIK, the entire point of that reference platform is that nothing is "very unstable" or even "unstable" but instead a stable target to develop against. I'm guessing adding something like that would defeat the purpose somehow, and risk getting studios vary enough to make it not worth it.
