Edgedancer? Dawnshard?

So I just finished reading Words of Radiance and I understand that both Edgedancer and Dawnshard aren’t necessarily part of the main story but are a part of the same universe, as connected by the interlude chapters. I’m wondering A.) would it detract from the main books if I didn’t read the interludes, and B.) if I were to read the interludes, should I read Edgedancer before I start Oathbringer or would it not matter if I chose to put them off until after I’ve caught up with Wind and Truth?
