[erlang-questions] ct:require and ct:get_config

It looks like a clause is missing or documented incorrectly for common
test external config:

It says you can require and get config paths up to 3-tuples like

require(Required)...

where Required = Key | {Key, SubKeys} | {Key, SubKey, SubKeys}

but in R15B01, only 2-tuples are implemented (ct_config):

require(Key) when is_atom(Key) ->
    require({Key,[]});
require({Key,SubKeys}) when is_atom(Key) ->
    allocate('_UNDEF',Key,to_list(SubKeys));
require(Key) ->
    {error,{invalid,Key}}.

Is there a specific reason for stopping at 2? Would a patch to fix the
documentation or to fix ct_config be preferred? If the latter, any
reason for not recursing down arbitrary depth of config tuple trees?
