Re: EXISTS variants

as a furter excursion in this direction, i applied a revised version of the
extraction process to the archived wikidata queries.
these, as described by the ICCL Wikidata query archive

    https://iccl.inf.tu-dresden.de/web/Wikidata_SPARQL_Logs/en

there were a total of 1,310,678,852 SPARQL queries, of which 626,080
included exists operators.
the attached graph depicts the operator count distribution
