What you mean is that 3GPP has chosen to go a different direction. The phonebcp procedures would work fine in IMS systems if operators chose to implement them. There is no inherent disconnect.
Phonebcp makes pretty sweeping statements about the way that emergency calls are placed, and makes a large number of statements instructing phone-centric behavior which doesn't work well for cellular phones. There are very small number of statements allowing in some cases for network elements to handle some of the phone-centric tasks.
