Hi Stephane,

if we do any changes to the core routing module, then I am afraid all modules 
that depend on it will have to follow suit. In particular, if we put config and 
state data into separate modules, protocol modules should do the same.

I don't like the idea of putting the core routing model and all work that 
depends on it on hold until we reach a decision regarding opstate. So, *if* the 
separation of config and state data gives a reasonable guarantee that at least 
the config part will be compatible with the ultimate opstate solution (whatever 
it is), it IMO makes sense to do it. But I am not even sure that the premise 
holds.
