That's really not good advice.

I'd caution against using link-local addresses for any type of service.

Link-local addresses are used for host-to-host communications on the
same Layer 2 segment. Routers will not forward traffic with link-local
addresses.

Besides, link-local addresses are automatically created. They cannot be
guaranteed to be unique anymore than they can be guaranteed to be constant.

Mark.
