Most of the components (except bean and mock) below package components are not referenced from the rest of the camel code. So my suggestion is to move these into a separate maven project that could be called camel-components-standard. The new project will of course include camel_core but camel_core will not need to include the components.
The only components that are heavily referenced from the rest of the camel_core are bean and mock. These will have to stay in the maven core project of course.
The separation will make understanding the camel core code easier as it gets smaller.
