Thanks. I'm aware and already deprecated rule that goes the other way around:
rectorphp/rector-symfony#854

Also, might not be doable for real configs like framework bundle, doctrine, monolog, security etc.
They're more complex with optional nesting.

How would something like this look like?

 $dbal = $dbal
        ->connection('default')
            ->dbname('database')
            ->host('localhost')
            ->port(1234)
            ->user('user')
            ->password('secret')
            ->driver('pdo_mysql')
            ->url('mysql://db_user:db_password@127.0.0.1:3306/db_name') // if the url option is specified, it will override the above config
            ->driverClass(App\DBAL\MyDatabaseDriver::class) // the DBAL driverClass option
            ->option('foo', 'bar') // the DBAL driverOptions option
            ->path('%kernel.project_dir%/var/data/data.sqlite')
            ->memory(true)
            ->unixSocket('/tmp/mysql.sock')
            ->wrapperClass(App\DBAL\MyConnectionWrapper::class) // the DBAL wrapperClass option
            ->charset('utf8mb4')
            ->logging('%kernel.debug%')
            ->platformService(App\DBAL\MyDatabasePlatformService::class)
            ->serverVersion('8.0.37')
            ->mappingType('enum', 'string')
            ->type('custom', App\DBAL\MyCustomType::class);
};

I think this will need to mature a bit ;)
