I was thinking about how there are nearly 900 episodes of Star Trek. And while there are references to older episodes galore, especially in the reference-machine that is Lower Deck, I realised that, realistically speaking, a lot of them made no impact on the franchise whatsoever.
By that I mean, so far there are no references to the episode in other episodes at all and nothing important happened in it that made a lasting impact. The truly forgettable episodes. This includes films as well. After all, I don't think Insurrection really made any impact.
I also imagine that a lot of episodes haven't been explicitly referenced, yet still contained important character development that can't be skipped. Essentially, which episodes could be completely erased from history without affecting anything else whatsoever?
