About JSONB_PATH, you said that "JSON null value is considered equal to
other JSON null values", but didn't say anything about IS DISTINCT FROM at
jsonb_path level. Wouldn't be good to mention something about it ?
select '{1,2}'::integer[] is distinct from null::integer[]
select jsonb_path_exists('[null]', '$[*] ? (@ == null)')

Marcos
