^ Exactly....she is a symbol and path for Peter, in his future relationship with MJ, and the approach & caution he will convey when he become involved with her. He will never live it down after promising Cap. Stacy...and if Marc stays true to the comics version, Peter will forever question himself whether he kill her directly or indirectly. Which will give more purpose to Gwen death if Marc stays faithful to the comic adaption of both Gwen & MJ; because, Peter sincere approach and concern for his future relationship with MJ will be in direct conflict with MJ's more free spirit, adventurous, sometimes reckless, party-girl persona....and that's what I feel is being setup with the Death of Gwen Stacy. Not to take anything away from that iconic moment...but adding to the legacy of it down the line, when Peter become involved with MJ.
