[jax-rs-spec users] [jsr339-experts] Is ParamConverterProvider needed ?

We have ParamConverterProvider and ParamConverter, I wonder do we really
need the former ?

Example, individual ExceptionMapper implementations can be registered as
providers, why should ParamConverter implementations be created
indirectly via ParamConverterProvider ?

I can see ParamConverterProvider allows to find the providers for
arguments like "List<Book>" - but do we really need it ?
