I've been following the list for some time now, and this topic of punctual changes in birdc conf with or without the need for a complete reload is always coming back, and it's always a complex topic...
>From simple things like adding a route, updating a prefix-list... Even with things like adding a new peer. This is certainly not a simple thing to address. But it is a pain that attacks several scenarios. I'm sure the developers have already had deep conversations about this, and that SMP has a higher priority. But could you just mention what possibilities were considered to resolve this issue?
