One thing that I have not been able to find is the neighbour stuff:
Since Babel has its own neighbour discovery sub-protocol (Hellos / I
Heard You's), I don't strictly need to use the core mechanism, I guess,
but I started out using it anyway since I thought it might gain me
something. But I haven't seen any neighbour events in any of the testing
I have done yet.

So what events cause a neighbour to go away / come back as far as the
bird core is concerned? Is it just the obvious case of the interface
going up/down and gaining or losing addresses? Or is there something
smarter?
