There is a third option... - The onus is on the constructor of the "merge" key. The question is the API used to load the key/value pair, based on the tags of the key and the value. Naively, it would return a single (key, value) tuple. However, if it is allowed to return a list of (key, value) pairs... Or simpler - allowed direct access to the mapping it is being loaded to, and calls "add" or whatever any times it wants. The same issue may be raised by other "magical" tags.
