Honestly, I think that removes all value of the stable series. I
remember when the stable series were first created. People were saying
that it wouldn't even get to more than 5 versions, because the bar for
backporting was suppose to be very high. Today it's just a fork of the
kernel at a given version. No more features, but we will be OK with
regressions. I'm struggling to see what the benefit of it is suppose to
be?
