I don't think that's necessarily the case, but I do agree of course that the recoverability story is really important for all encryption features, whether full-disk or home directory level. @sonny may be able to provide more detail on the specific goals.

Why encrypting home directory individually rather than say full disk encryption?
1. Keep users safe from each others
2. Improve the user experience and encourage adoption
The design team is looking at the options for recovery.
