I'm trying to think how else it could work, and I'm drawing blank. Since
when neighbour has been set with SoO, you will have to send different
routes to that neighbour, as you omit sending any routes that already
have that SoO set.
I guess SoO could have been implemented as some filter post update-group,
but that would have introduced more complexity.
