Larry, Can you explain the use cases for such hooks? Most of computation should be done while the DIC is being built so on a standard request no important computation is done.
So if my understanding is good, the DIC should contains all configurations and hooks must be replaced by an Events to only alter the targeted data (ie, the node, the form ...) based on services definitions. The "tell me about yourself" must be done when the container is built by using mechanism from the Dependency Injection Component. Now, I don't know the current implementation in Drupal, but in Symfony2 (the full stack framework), there is no "information" metadata where a bundle can register or provide information about what features a bundle implements.
