It does not give any extra benefit because tmpfs only resides in RAM, and disk encryption typically only concerns data at rest.
If you come to a point where you want to have /tmp/ encrypted, you would rather encrypt the whole RAM. (Does anyone actually do that?)
AFAIK the main benefit is: if you want to run a multi-user or headless system, you need the network stack brought up before a password is entered - which home directory encryption provides and FDE can't.
