Good story telling is what matters. Adherence to continuity should never be more than a secondary issue at best.
Well if you are contradicting a past episode, especially heavily contradicting, you are at least suggesting that your storytelling is better (since the past episode is to be ignored) so it should be.
Anyone who values adherence to continuity with a 51-year old show over telling a ripping space yarn that adheres to the spirit of that old show, if not the letter, is a crazy person.
I don't think Kurtzman, Fuller or Goldsman have written a lot of good or better stories (though Meyer has) so I'd rather they didn't contradict and cause to be ignored or dismissed older stories including ones that were better.
