Why should the foreign_key_list pragma continue to consume code space and developer maintenance time? Because it lets me introspect the schema, and write code (or code generators) that depend on the logical structure of the schema, without having to parse the DDL myself. For example, it makes it easier to undo cascading deletes. Given the foreign_key_list pragma, I can determine the tables that depend on a given table, and then target triggers to those specific tables to capture the undo information. Why get rid of introspection that already exists? If code space is the big deal, make it an optional part of the build.
