Is it possible to use keylocation=file:///path/to/keyfile for keyformat=passphrase?

The only concern that I have for single key slot is that I could lose the key file.

But, if I remember the passphrase, I can reconstruct the keyfile.

Is this possible?

It seems that this is entirely possible. Thus, I don't need multiple key slots!!!!! Yay!!!
