I agree, although I'm not entirely sure I understand what you are suggesting. The JDO spec has a rather confused view of what the jca spec says (I'd guess 70% of the specific feature references are wrong in some detail) but the basic idea they have is that a jdo implementation must expose the spi interfaces if it wishes to be useable in an app server. I thought Castor might be improved by changing its jdbc access to be to a jca-wrapped jdbc driver, thus making it easy to expose the spi interfaces. I'm not sure of the value of trying to expose cci outside of jdo. The jdo-style object navigation is more java-like and easier to use than cci. I think the use of cci is in supporting either a jdo implementation or cmp2 beans. IMHO cmp2 is kind of similar to jdo access. cmp2 has (at least in jboss) easily extensible metaprogramming interfaces (the spec includes transaction and security support for instance) whereas jdo handles inheritance and polymorphism better.
