-----------------------------------------------------------
Adding syntactic sugar is unnecessary right now, {{RenderKitUtils}} can be
extened instead.
Let's revisite in the future.
----
There are two other solution then extending {{RenderKitUtils}}:
* adding stateful auxiliary object which would carry {{facesContext}} and
{{component}} references to, e.g.: {{renderingContext}} or {{componentContext}}
* using auxiliary tags, like in case of {{<cdk:renderFacet proposal />}}
