I listed the issues SLING-3533, SLING-3534, SLING-3535 and SLING-3619 at the bottom of my mail and I've now created a new issue SLING-4223 to track your request and a new version (2.2.0) for JCR ContentLoader. We will need to find a way how to get the right ContentReader for a format as we will have the same extension (e.g. .xml, .zip) for different formats.
