There is no clojure.core/dissoc-in although there is an assoc-in. It is correct that dissoc-in can be build with update-in and dissoc but this is an argument against assoc-in as well. When a shortcut for assoc-in is provided, there should also be one for dissoc-in for consistency reasons. Implementation is analogical to assoc-in.
