Well, we do ship a default JSONProvider which assumes objects are JAXB beans -
those will be automatically mapped. On top of it we can customize a lot
JSONProvider works with data. Thus we can't drop it and replace with Jackson or
XMLStream provider.
We can also application/x+bar medium type and MyObject - would you expect it
automatically mapped as well ?
The point I'm making is that we ship a default JSONProvider. And registering
custom or existing 3rd party providers is very easy. Even if CXF did ship say
XStream provider then you;d still need to register it explicitly for it to be
preferred to the default JSONProvider - but I don't think we can afford
shipping multiple JSON providers
