Assigning null to a key in the MultiDictionary will not delete that key (this behavior is symmetric with the behavior of querying the values under a key where null indicates that the key doesn't exist - it also doesn't add any "secret tricks" because the normal Dictionary doesn't intersect this functionality of having an extra container between the key and the values)
