I have never disputed that things might be clumsy now, I just think 
we should focus on getting the flowscript way better, instead of 
adding things that makes the sitemap more of a programming language, 
by handling a more diverse set of datatypes then strings.

This one is absolutely same issue you are discussing here:
  http://issues.apache.org/bugzilla/show_bug.cgi?id=9916
IMHO, it is worth to discuss the issue of passing object parameters by 
itself, without mixing flow or jx into it, as a bonus we might get 
resolution for a 2.5 years old feature request.

As for implementation, probably extending Parameters with 
getParameterAsObject, setParameter(String, Object) should be enough.

And changes to VariableResolver so that it returns an object if it only 
contains an input module expression.

We can add getParameterAsObject() to o.a.c.sitemap.SitemapParameters 
that was created to add getStatementLocation().
