Perhaps the clearest way to see what is available is to look at https://www.apple.com/legal/privacy/law-enforcement-guidelin... to see what information is available.

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.
