It's not a yes-or-no question.
If I'm allowed to elaborate on what I mean, the non-derogation clause alone would act as a reminder that first nations have rights in this case only because of the broad wording of clauses 8 and 9 under “Métis Governments” in Bill C-53. The rights described there are very broadly written, so a non-derogation clause would act only as a reminder that, “Oh yeah, first nations have rights too.”
