i asked claudio about this. with his permission, i'm forwarding his answer: site-local addresses are deprecated but you can still use them on a interface. Unique local addresses more or less replaced them. I don't like to use fd00::1 and fd00::2 because per RFC 4193 the first 48bit of the address should be created per site. Section 3.2: The allocation of Global IDs is pseudo-random [RANDOM]. They MUST NOT be assigned sequentially or with well-known numbers. This is to ensure that there is not any relationship between allocations and to help clarify that these prefixes are not intended to be routed globally. Specifically, these prefixes are not designed to aggregate. So in the end either solution is not perfect at the moment I would keep the example as is.
