Yes, you've said the power over the language from 1867 is rather archaic now, but the power over “Indians, and Lands reserved for the Indians” is not limited to things that are under other federal heads of power, and so it is a unique power and it does capture a lot of powers that are thought of as provincial powers, property and civil rights, that sort of thing. It turned out to be very useful that it's not a narrow power, it's a wide power, and coupled with some co-operative assistance from other levels of government, I can see this could be good.
