Can I suggest that we also include the provision to rollout an
out-of-schedule release whenever we deem it necessary? So effectively
the regular schedule would be the **maximum** time between patch
releases. That may help to alleviate Andreas' concerns, as we could
always push out an out-of-schedule release if there's sufficient
number of high-impact fixes ready.
