 So I guess a SRU backport to jammy is not possible? (re @mitya57: It has private ABI breaks, so it will be part of 5.15.4 transition in May, most probably.)
 Yes, impossible. Maybe you can add it to some Kubuntu PPA, though.
 But the abi break would break some things, no? Or do you mean a PPA where things are rebuilt against it? (re @mitya57: Yes, impossible. Maybe you can add it to some Kubuntu PPA, though.)
 Potentially yes. But I don't know for sure — it needs testing.
 Ok, I will think about that
 But at least I can now answer the redditor who asked. Thanks :D
