Are the Sinixt still considered extinct?

Canada’s Supreme Court recently granted the Sinixt hunting rights in their traditional territory. Some celebrated this as a reversal of the declaration of extinction of the Sinixt people by Canada in the 1950ies. But others say it’s not, as they still don’t have land rights.
