There are plenty of non-LE use cases, such as people who need to recover access after a lost password, as well as families who want access to a deceased family member's information after the fact.
Apple has been (slowly) adding support for other recovery systems and for legacy contacts as first-class features. The UX for this currently lists Apple as a fixed option among a list of other options (such as personal contacts).
I expect long-term that Apple will have access to backup recovery for a number of people as a system default, but not for everyone.
