Does anyone use LISP (Location Id Separation Protocol)?

In the CCNP ENCOR, Cisco tries to sell us LISP. However I am struggling to find any decent use cases.

I have seen a youtube video of someone migrating a datacenter from one physical place to another, and used LISP instead of a L2 overlay technology, with one of the reasons being to avoid spanning-tree calculations.

However, I struggle to find a good reason as of why would someone go to this trouble.

I mean, I know that there are 10 year old technologies for roaming in wireless networks and that seems to work with a click of a button, but does anyone really need to roam around with static wired IP addresses among campuses? Or am I missing the big picture here?
