[question] fscrypt recovery - and the mechanics behind it

How long until `fscrypt recovery` will be a thing?

I've had my ass saved at least once in the past by keeping an unwrapped ecryptfs key safely stored, and I'd appreciate having that option again.

> fscrypt supports the idea of of protecting a single directory with multiple protectors. This means having access to any of the protectors is sufficient to decrypt the directory.

Can I assume this is "Protector" file contains encrypted keys to encrypted policy files, which contain key/salt for FS policy? Or does it do something more complicated under the hood?
