small proposal that seemingly does not exist yet:

/** merge another map into this map,
 * storing the result of applying the given remapping function to the two values if there is a key-conflict. */
fun <K, V> MutableMap<K, V>.putAllWith(other: Map<K, V>, remappingFn: (V, V) -> V) = other.forEach { (k, v) ->
    merge(k, v, remappingFn)
}

any maybe a matching plus-like operation (unionWith?)

Wouldnt a better name be mergeAll or simply an overloaded merge ?

possibly yes, you're right
