Konrad Windszus commented on SLING-7624:
----------------------------------------
[~jsedding] Let me quickly outline the reasons:
* {{@SlingServletPaths}} and {{SlingServletResourceTypes}} is separated because
for the latter a lot of additional restrictions may be maintained (selectors,
extensions, methods), while for the former this is not supported. Having both
types supported with the same annotation would lead to a lot of elements which
would only make sense for one type
* {{@SlingServletPrefix}}, basically [~cziegeler] asked for a separation in
https://issues.apache.org/jira/browse/SLING-7624?focusedCommentId=16473614&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16473614.
The main reason is that prefix is rarely used and actually the same property
is used for both servlet types (registered by type and by path). To make that
clearer a common dedicated annotation is provided for that.
* {{@SlingServletName}} is a dedicated annotation for very similar reasons as
for {{SlingServletPrefix}}. In addition this property is not really bound to
registering servlets at all.
* {{@SlingServletFilter}} is actually just a single annotation.

> Previously there were annotations hosted at Felix for Sling Servlets/Filters
> as custom Felix SCR annotations
> (https://github.com/apache/felix/tree/trunk/tools/org.apache.felix.scr.annotations/src/main/java/org/apache/felix/scr/annotations/sling).
> With OSGi R7 and DS 1.4 component property annotations are specified. Sling
> should provide those annotations in a dedicated new artifact. Compare also
> with FELIX-5396.
> Those are supported in the upcoming bnd 4.0
> (https://github.com/bndtools/bnd/issues/2163).
