Personally, I would recommend it wherever possible. It saves you the step
of "show ipv6 interface" to look at the address, and typing or cut/paste
ugly addresses. Worse, when looking at routing tables, nothing makes sense
because we typically don't memorize MACs.
Just my two cents. But I'd define them wherever not otherwise prohibited!
Example "ipv6 address fe80::6 link-local" is going to be R6 on every
interface. East to remember, easy to visualize!

Thanks you all.
One more question, should you explicitly configure for "ipv6 address
link-local" for the interface during practical lab?
