If you look at the target use cases
https://sling.apache.org/documentation/bundles/sling-query/vs-jcr.html
Almost everything that is listed as use "JCR-Query" is what I use the resource
locator for. So, as far as I'm aware, they are complimentary .
I also took a different approach to the API. The resource locator was built
around the Stream API and predicates. You don't even need to use the
ResourceLocator object
Example
aChildResource("jcr:content").has(property("sling:resourceType").isNot("sas/components/page/folder")))
creates a java.util.function.Predicate<Resource> object that could be used any
where you need to filter a stream of resources, like a stream() from a
Collection. The filter language creates a Predicate<Resource> object as well.
I haven't checked sling-query yet but my filter language does a lot of heavy
lifting for you. Handles arrays, conversions between types etc.
