i don't see the appeal. what is the benefit over 256 bit? i can see
two things maybe:

1, performance. but it kinda tops at 512 or 1024 bits these days. why go higher?

2, hides more information in disk encryption like scenarios where you
can't store nonce/IV. personally i don't think there is future to this
kind of encryption, but that's another issue. the main issue is, why
would we want a special block cipher for this reason, instead of some
hotfix mode of operation, like the abandoned elephant diffuser was.
