Using APC with PHP 5.5+ and Zend Opcache

Now that PHP 5.5+ shipd with Zend Opcache for a PHP opcode caching mechanism, what is the plan for this module to leverage that?

I'd like to gain some insight and develop some instructions on how best to use the Zend Opcache for my sites' opcode caches, but APC (or APCu?) still provides the other caching mechanisms which Zend Opcache does not such as user session data and file caching.

My understanding of the PHP 5.5 Zend Opcache is that it outperforms APC in its designed role, but I have not benchmarked this on my Drupal sites myself. Does anyone have any insight on performance metrics to compare these options for hosting Drupal sites specifically?

Will this module continue to provide support for APCu as Zend Opcache takes over the opcode cache role? And if so, which Drupal caches would best be placed into APCu and which should not?

Any guidance and documentation on these developments in the PHP community are greatly appreciated. Thanks.
