On needn't argue this; it is explicitly stated in the EXPLAIN documentation (https://www.sqlite.org/lang_explain.html): "The output from EXPLAIN and EXPLAIN QUERY PLAN is intended for interactive analysis and troubleshooting only. The details of the output format are subject to change from one release of SQLite to the next. Applications should not use EXPLAIN or EXPLAIN QUERY PLAN since their exact behavior is variable and only partially documented." -- D. Richard Hipp drh at sqlite.org
