And the invoice goes... to the ASF?
Where can I raise the issue? I don't think I have write access to the Sling
Jira.
And what would be the best approach? Re-activate the
org.apache.sling.commons.json package?
Thanks, Juerg

Thanks Daniel, John,
As the app makes high usage of dynamic JCR Node features (based on
nt:unstructured, mixins, etc), a relatively static sling model class
seems a bit unpractical, though a typesafe contract would be
desirable,
of course.
On the other hand, the JsonItemWriter would almost be ideal but is
not
present in Sling 11 anymore. Actually, the entire commons.json
package
disappeared. Seemingly, this package has been replaced by Apache
Johnzon
but I cannot find anything equivalent to JsonItemWriter.
Anybody aware of its substitute?
FWIW, the rendering in the DefaultGetServlet is not accessible to the
outside world [1]. I could imagine that we could open on the default
renderers in ways that do not break encapsulation.
Feel free to raise an issue if that's interesting to you. Obviously, a
PR would be even better :-)
Thanks,
Robert

You could also use a JsonItemWriter and write your own servlet if
you want to do it that way:

Sounds like a use case for Sling Models Exporter:
https://sling.apache.org/documentation/bundles/models.html#exporter-framework-since-130-1
https://blogs.perficient.com/2018/07/26/no-servlets-required-exporting-data-with-sling-models/
The only caveat is that it's designed for named parameters, if
you really
need it to be completely configurable at runtime, I'd suggest
creating a
servlet attached to a resource type that filters the current
resources
value map and uses Jackson to convert it to a JSON.
