Some "Thinking out loud" here... My last concern with assoc-in & arrays has to do with how it is currently used for maps. The way it creates elegant nested structures is nice, and it requires very little understanding of the current structure of the map.
However, assoc-in has a few more constraints when dealing w/ arrays, and the end user does have to keep track of array structure. Granted they have to do this anyway by the nature of arrays. I personally always use conj when creating a vector of vectors, so I don't se much of a use case (Hmmm... Sparse Matrix? That's better as a map...). I DO see a great use case for update-in-with working on vectors, so maybe assoc-in-with working on vectors should be implemented simply for symmetry. I dunno. That's all I've got right now.
