ipv6 - link local uses

I understand ipv6 has some very interesting and very different things from
ipv4.

One of which is this link-local business (fe80::/64 as I recall), seems to
be an automatic ipv6 address on pretty much every single ipv6 product that
I've laid eyes on.cisco, linux, windows.

Question, is it possible, furthermore, is it a best practice to run purely
link local subnets between routers? OR must I configure real-world ipv6
address (I think called aggregatable global ucast) between my routers ? ..
I would understand the need for agg global's on customer facing interfaces
but on the router to router links...that's where I'm wondering.
