Using NAND in all the chips?

Is it necessary to build the chips using NAND? So far, I've built my way up from the NOT chip to the MUX chip, and the only time I explicitly used NAND was for building NOT, AND and OR. Of course, whenever I use these, I am implicitly using NAND.

Is this fair game? It would seem so to me, but perhaps the book was implying that all the chips in this chapter should be built explicitly using NAND?

Should I go back and re-do chips such as XOR and MUX to include NAND for the sake of having a better understanding of logic design?
