It's a TNG thing. Just like the Holodeck and Q is a TNG thing. Leave them out of Kirk era movies.
The holodeck is a TAS thing (The Practical Joker
) and Q is just reuse of the Trelane concept (The Squire of Gothos
Why can't I have a Kirk vs. Borg film? TNG used all types of characters/races/concepts from TOS.
