Speaking up for the crowd that would prefer to keep canon divergence out here. Labeling a story with a genre should give a feel for what the story is, even if it's a parody, deconstruction, etc. of that genre, and canon divergence is definitely too open to be a genre. Any of the genres listed could be a canon divergence AU (e.g. character development by exploring a divergence AU, getting-together through a soulmate AU, etc.). I think some people might be a bit confused by the definition of genre, especially as used in this post, but this is my understanding of the OP's definition of genre.
