Bringing this to devel at l.o where we are already discussing this issue.

So the problem is that if you had to resync all state for each machine
every time they wake up, you would use lots of bandwidth with the
power consumption associated, so much that it may not have been worth

Another issue with this is that you not only want to resync presence,
but shared activities also would need to resync their state. Which
cannot be done without activity-level support which we don't have. It
would also cause more traffic and power consumption in the network as
a whole.
