Kingsley,
thanks for suggesting that feature. Since you already have that feature,
could you let us know how often the UI option for these output formats are
used? That could help with prioritising.
My uninformed hunch would be that there isn't much demand for selecting the
format via the UI, and that is more relevant to have automated calls be
able to do that format selection, which the endpoint provides.
Thanks,
Denny

If the challenge is downloading large files, you can also get local access
to all of the dumps (wikidata, wikipedia, and more) through the PAWS
<https://wikitech.wikimedia.org/wiki/PAWS> (Wikimedia-hosted Jupyter
notebooks) and Toolforge
<https://wikitech.wikimedia.org/wiki/Help:Toolforge> (more
general-purpose Wikimedia hosting environment). From Toolforge, you could
run the Wikidata toolkit (Java) that Denny mentions. I'm personally more
familiar with Python, so my suggestion is to use Python code to filter down
the dumps to what you desire. Below is an example Python notebook that will
do this on PAWS, though the PAWS environment is not set up for these longer
running jobs and will probably die before the process is complete, so I'd
highly recommend converting it into a script that can run on Toolforge (see
https://wikitech.wikimedia.org/wiki/Help:Toolforge/Dumps).
PAWS example:

That isn't my challenge.
I wanted to know why the WDQ UI doesn't provide an option for CONSTRUCT
and DESCRIBE query solutions using a variety of document types.
See:
https://wikidata.demo.openlinksw.com/sparql to see what I mean.
Ditto any DBpedia endpoint.

Do these CONSTRUCT queries return any of the following document
content-types?
RDF-Turtle, RDF-XML, JSON-LD ?
you can use content negotiation on the sparql endpoint
~ query="CONSTRUCT { ... }"
~ curl -H "Accept: application/rdf+xml"
https://query.wikidata.org/sparql
--data-urlencode query=$query
~ curl -H "Accept: text/turtle" -G
https://query.wikidata.org/sparql
--data-urlencode query=$query
