It was during early 2014, or late 2013, so it would be hard to find the discussion. I do remember some of the points used to determine the existence of the TRN:


 * When characters have been brought from the past, they usually come from alternate universes. Teen Tony is an example.


 * A TRN helps differentiate the younger from the present versions of the characters.


 * Iceman, Angel and Jean Grey have all developed abilities and powers since they have been in the present. So, all of those developments should be reverted when they return to the past if they are to make sense in continuity.
