The CDIProvider serves as a kind of SPI for CDI's static methods to be 
able to call into the implementation. I don't think reusing it also as a 
user-facing code is a good idea. What people suggesting to reuse 
CDIProvider had in mind, I think, was to reuse it as the SPI for talking 
to the CDI implementation instead. That way, the initialize() static 
method of CDIContainer/StartedCDI/whatever we call it can use 
CDIProvider internally to actually start the container.

In addition, the current proposal does not make it possible to implement 
parallel container instances.
