Is it really necessary to flush entire site cache on XMLRPC request?

The line here:

https://github.com/pkhamre/wp-varnish/blob/master/wp-varnish.php#L111

// When xmlRPC call is made
add_action('xmlrpc_call',array($this, 'WPVarnishPurgeAll'), 99);

Causes the entire site to be flushed with fairly high frequency on Wordpress installs where users use mobile apps to submit stories. Is it really necessary? There are already highly targetted hooks that purge specific pages when an article is added, deleted, etc.
