good question.

I tend to agree.

unlikely anyone backports printk message updates. I have quickly glanced
through stable-4.9 and haven't seen such backports. well, may be there
are some.

can tweak the warning a bit, probably. e.g. "if you are planning to
backport your change to kernels older than 4.14 then ignore this
warning". but not sure if it's worth it.
