That's a good question, and afaict it remains unanswered. As so often happens, this patchset's changelogs forgot to describe the reason for the existence of this patchset. Via a bit of lwn reading and my awesome telepathic skills, I divine that something in networking is using syslog for kernel->userspace communications. wtf? Wouldn't it be better to just stop doing that, and to implement a respectable and reliable kernel->userspace messaging scheme? And leave syslog alone - it's a crude low-level thing for random unexpected things which operators might want to know about.
