Issue for tracking integration into core

The project page states that there is hope to get this or something similar into core. Is there an issue thread to track to watch progress / direction that core takes?

I found an oldie: #218770: Drupal Pipes → ; Sadly this has seen little activity in the last couple of years.

I found little else searching on http://drupal.org/project/issues/drupal?text=Chain+Menu+Access&status=Op...

Cheers
