Think of that you want to Provision a "smart device" with just a computer and no router.

These link local addresses are quiet handy. But sadly the parsing of these with modern browsers is a flame war ever since. I assume that's the reason why we don't see its usage that often.

Another nice use case is to use these link local addresses in cloud environments...

mDNS allows you to access a local HTTP service via IPv6 without IP-based URLs, so it seems pretty relevant.
