HP:MoR does imply however that one needs extra-special power to destroy artifacts—e.g. the FiendFyre which in canon is one of the few things that can destroy a Horcrux, is also mentioned (not by name, but implicitly as a type of cursed fire) in HP:MOR by Quirrel as what would be used to destroy an artifact like the Sorting Hat.
So I don’t think Harry just snapping the Elder Wand in two could happen in the ’verse of HP:MoR.

It really shouldn’t have been allowed even in the movie. (NB: I haven’t seen the movie; I’m only relying on CronoDAS’s description.)
