It would make sense, I think, to add the "ii" variation as well. I wonder if it's necessary to provide the aliases \tlist_head:w and so on. I guess using them is a bit nicer than \use_i_delimit_by_q_nil:w. As a matter of style, should we also define \use_iii_delimit_by_q_nil:w as a counterpart to \tlist_head_iii:w ? W
