This was debated here, among the inspectors, and it was decided not to require such breakers for panel changes / service changes.
Indeed, they went even further, and decided not to ask for it when the actual circuit is worked on.
The reasoning was two-fold: first, until the AFCI requirement was introduced, bedroom circuits were almost never segregated from other circuits. Secondly, the lack of AFCI devices meant that the slightest work on a circuit that happened to serve a bedroom would require a service change as well.
How's that? Well, we have a lot of homes here still using fuse boxes - let alone breaker panels that are no longer available.
There is also the nightmare of shared neutrals in K&T installations. Someone wanting to add a receptacle, or even upgrade their service, ought not be required to re-wire the entire house.
