    If `$keys` is not empty, follows the `$keys` to find the nested map targeted
    for merging. If any key in `$keys` is missing from a map or references a value
    that is not a map, sets the value at that key to an empty map.

    If `$keys` are passed, follows the `$keys` to find the nested map targeted for
