Hi Felix,
I see scripts mainly as a mechanism to express rendering/behavior and
servlets serve the same purpose, so from my level of abstraction,
there is no conceptual difference.

Yes and no :-) On the one hand scripts are just a special case of
servlets. But then scripts are loaded differently that servlets.
Servlets are registered with the ServletResolver (either manually as
in
microsling or through the OSGi service registry as in Sling) while
scripts are dynamically resolved.
So, this is how the ServletResolver works:
1. Find a servlet for the resource type
2. Find a script for the request (mostly by the resource type again)
(this step delegates to the ScriptResolver)
3. Fall back to the default servlet
So, any solution involving the ServletResolver is inherently more
powerful than solutions limited to involve the ScriptResolver only. In
fact, we should not directly use the ScriptResolver and leave this to
the ServletResolver.

Felix
