PDO subclass names

Hi internals, Recently I've been working on an RFC regarding object support for BCMath. While working on that, I learned of the following RFC: https://wiki.php.net/rfc/namespaces_in_bundled_extensions If we follow this RFC, is it reasonable to place subclasses of PDO under the namespace "PDO”? e.g. ``` PdoMysql => PDO\Mysql PdoPgsql => PDO\Pgsql PdoSqlite => PDO\Sqlite PdoOdbc => PDO\Odbc PdoDblib => PDO\Dblib PdoFirebird => PDO\Firebird ``` We'll probably get a BC Break if try to fix this after 8.4 is released, so before it's released is last chance to fix this safely. If Tim's RFC under discussion is passed, the namespace will be "Pdo" instead of "PDO”. https://wiki.php.net/rfc/class-naming-acronyms I would appreciate hearing your opinions. Regards, Saki
