OK small silly example is convincing distributions it may be a good
idea to carry linux-next kernel packages as options to users to
hopefully down the road reduce the delta between what they carry and
what is actually upstream.

Right -- in this case above "others" could be developers but could
also be distribution guys. Essentially I was looking for arguments to
push and show why linux-next is the next best thing since sliced bread
for all those nasty deltas.

Which OK -- maybe they can never disappear (?) but hopefully it can at
least be reduced in size over time.

Heh.. Maybe I expect too much of people and things.
