The documentation for options merging doesn't describe the default behaviour for how arrays are merged.
Currently it seems that arrays will merge by position, that is merging [1, 2, 3] onto ["a", "b", "c", "d"] would produce [1, 2, 3, "d"]. It also appears that if you want a shorter array that the original you'd need to specify a merge policy of "replace" for that option path.
