Basically there are two "Fabric Reconfigurations":
1. BF - Build Fabric which is non-disruptive
2. RCF - Reconfigure Fabric whihc is disruptive.
An RCF is only used if a discrepancy is observed in the fabric structure such as multiple principle switches in the same fabric or incorrectly used domain-id's where usual segmentation doesn't seem to occur. In this case all FC sequences are terminated, all domain-id lists are cleared and a new configuration is build via the normal EFP process. A principle switch selection occurs and the usual domain id distribution happens.
A BF does the same exept it does not terminate inflight sequences or class-1 connections. If you add a new switch then normally this BF is what happens.

If there are multiple switches in your fabric and you need to retire a switch that is currently serving as the principal switch, what would happen when that switch is removed? Does it go thru a RCF when a new principal is elected from the remaining switches?
