But I worry that replacing `wdt:P279` with `(p:P279/ps:P279)` will also degrade performance significantly. If best-rank statements don’t give the right result, shouldn’t that be an incentive for users to fix the subclass tree? After all, most other queries will presumably also use `wdt:P279`. (In the 2018-02-26 SPARQL logs <https://iccl.inf.tu-dresden.de/web/Wikidata_SPARQL_Logs/en>, I count 542 queries using `p:P279` against 251338 queries using `wdt:P279` in the “organic” set, or 1485 `p:P279` queries against 10112191 `wdt:P279` queries in the “all” set.)
