    How about this - Kevin did it because (1) it improves Cayenne and (2)
    he felt like doing it. Every day we hear "I am using X, so X has to be
    the most popular technology out there, so you must make it your
    highest priority to integrate with X"... Fine, except that "X" is
    different for every person, and at the end we have the entire alphabet
    to take care of.

    Technically both Maven and Ant plugins are trivial, as there is a
    class in Cayenne core called DbLoader. However doing a production
    quality work means writing the code, unit tests and documentation.
    This means someone spending more than a few minutes on that.
    Everything can't happen overnight. Second guessing the developer
    priority is not going to help here.
