Let's do this the other way around and be react based on facts and not
speculations.
Let's change the policy for a year for selected packages as I
outlined, monitor bugs and after a year see response times, affected
users and if downstream patches are accumulated. Then we can decide if
we need to patch upstream packages.
If we need to patch upstream package anyway, not follow upstream
policy and not accepting input for various of permutations and
architecture from all users, this discussion is nearly void.
