Having a set of examples might be helpful for users experimenting with the graph split.
A subpage under https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/WDQS_graph_split might be appropriate.
The set of queries to rewrite could be sourced from the samples used in T355040.
An example should consist of a query that requires scholarly articles and its rewritten form. Ideally the results should yield identical results when applied to the global graph and when applied to the splits.

AC:

• a new subpage of https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/WDQS_graph_split is available with several (between 5 and 10?) examples queries federating query-main-experimental.wikidata.org and query-scholarly-experimental.wikidata.org.
