Re: TNG's "Too Short a Season" with Kirk...
Well, the revised final draft was written a year after Star Trek IV came out, so the TOS cast was still coasting on that, and Shatner's contract gave him the right to direct the next film. So that could come into play as well.
Memory Alpha seems to make no mention of a Shatner or "Private Little War" connection, so we all may be suffering communal influence from all those encyclopedias and episode guides and technical manuals we're always buying.
