Description

In JSP there is the possibility to include a resource in a component and adjust the suffix of the sub-request, processing this resource:

<sling:include 
    path="my-component"  
    resourceType="application/components/other-component"  
    replaceSuffix="some-suffix"/>

See also: https://github.com/apache/sling-org-apache-sling-scripting-jsp-taglib/blob/7835da79f1de7c9c14fd478e9fec23f54fd6d711/src/main/java/org/apache/sling/scripting/jsp/taglib/AbstractDispatcherTagHandler.java#L89

But HTL lacks this option to adjust the suffix for the sub-request (by using data-sly-resource): see https://github.com/apache/sling-org-apache-sling-scripting-sightly/blob/3b50f91c4f600081f0585e50dfb775c4b2856b89/src/main/java/org/apache/sling/scripting/sightly/impl/engine/extension/ResourceRuntimeExtension.java#L58 

Is there a reason why this feature wasn't added and is not supported right now?

Because we can manipulate the suffix in a URI context in HTL (https://github.com/apache/sling-org-apache-sling-scripting-sightly/blob/3b50f91c4f600081f0585e50dfb775c4b2856b89/src/main/java/org/apache/sling/scripting/sightly/impl/engine/extension/URIManipulationFilterExtension.java#L221), but just not in the Resource context.

The RequestDispatcher is already available and used in the ResourceRuntimeExtension so it could be added.
