Dear Wikidata developers and contributors,
I see that it is currently not possible to run federated queries from wikidata to other sparql endpoints. I understand why you are not allowing this in the general case. However, it would be nice to allow this in the special case.
Would a patch allowing limited known remote sparql endpoints to org.wikidata.query.rdf.blazegraph.WikibaseContextListener be possible?
