No Horror Stories, everone told me that the SUNs will happily run all-1.
However, since we'll be blessed with improved Routing/Filtering real_
soon_now (tm), the Need to switch over has reduced in Priority and I
didn't try Things out yet.
As a Sidenote, nobody was yet able to explain how "Broadcast Storms", the
reported Danger of mixed-Mode Networks, happen, so I *will* change once
the Netmasks etc. get nailed down, just to be on the safe Side.
