nb_lookup returning a list only with more than 1 item

[bluikko]

I would like to question the behavior of the nb_lookup plugin.

If it returns more than one item then it of course returns a list. But if it returns only one item then it does not return a single-element list.

Would it not be more consistent to always return a list, even if it includes only 1 element?

edit: if the API is queried directly with, say, the stock uri module, it is simple to always find json.results a list - even if there is only a single item.
