Discovery's Legacy

Randomly watching episodes of older Star Trek, and two off-hand references caught my attention after watching Discovery:

In TNG's “First Contact” (The episode, not the movie), Picard mentions that a 'disastrous contact' with the Klingons led to decades of war. That's not what happened when Archer first made contact with the Klingons in Enterprise... but that's pretty much exactly what happened on Discovery at the Binary Suns.

And in DS9's “Once More Unto the Breach”, Kor talks about a great victory he won over the Federation as a young man, at Caleb Four, when 'the cloaking device was a new technology' and only a few engineers could operate them. That... pretty much slots perfectly into the Klingon war as portrayed on Discovery.

Someone on the writing team, I think, has a very keen head for trivia and obscure continuity.
