Module dependencies error in bookexpand.info?

The current (bookexpand-5.x-1.0.x-dev.tar.gz) download includes this line in bookexpand.info:

dependencies = og views views_rss book

But 'og' is not required to run this module. It is simply an option for access control (not a requirement). It might be suggested, but you should be able to use the module without og. AFAIK, Views isn't required either.

In my installation, I changed the line to:

dependencies = book

Which I believe is more correct, unless there is a reason why both Views and Views RSS must be installed? I can't see any reason in the code.

After doing so, the $options array in settings: $options = array ('None', 'Role', 'Group', 'User', 'Private'); should check for the existence of the OG module (and other suggested dependencies).

Similarly, bookexpand.install should only install the og_book table if og is installed.

function bookexpand_install() {
 if (module_exists('og')) {
    switch ($GLOBALS['db_type']) {
      case 'mysql':
      case 'mysqli':
        db_query("CREATE TABLE IF NOT EXISTS {og_book} (
          `og_nid` int(11) NOT NULL default '0',
    	  `book_nid` int(11) default NULL,
	  PRIMARY KEY  (`og_nid`)
          ) /*!40100 DEFAULT CHARACTER SET utf8 */;");
    }
  }
}
