That will mostly be 'dead horses' that we do not really like to ride.
Devuan despises Debian and does not trust it, the majority of its developers and its community. So same will go for siduction. I have been sitting in their channels since they opened and have been called a troll at least 50 times, probably more. That NEVER happened to me in any other channel. So no, I do not think there will be much collaboration.
