The CDI SPI is not backwards-compatible after CDI-96. For example:

• InjectionPoint.getBean() now returns BeanAttributes instead of Bean
• AfterBeanDiscovery.addBean() now accepts BeanAttributes instead of Bean

The spec, Javadoc for the given methods as well as the fact that these changes cause backward incompatibility indicate that they are a result of accidental batch modification and not intentional.
