Debate continues as to whether the Pacific Coast languages form a valid genealogical grouping, or whether this group may instead have internal branches that are tied to different subgroups in Northern Athabaskan. The position of Kwalhioqua–Clatskanai is also debated, since it may fall in either the Pacific Coast group – if that exists – or into the Northern group. The records of Nicola are so poor – Krauss describes them as "too few and too wretched" (Krauss 2005) – that it is difficult to make any reliable conclusions about it. Nicola may be intermediate between Kwalhioqua–Tlatskanai and Chilcotin.
