Note, this patch adds new values in the middle of the enum. This is in general a breaking uAPI change: all enum values afterwards will get re-numbered.
Maybe this patch should come before the PQ 125 one. In this series it shouldn't matter either way because we're also introducing the enum, but (1) who knows what/how distros might end up cherry-picking (2) future patches might take inspiration from this one.
