We had a discussion here on the merits of SHA-256 over SHA-512 with the
two arguments I already mentioned:

  - SHA-256 is much faster on smaller 32 bit systems
  - SHA-256 is anyway required to verify existing signatures.

An advantage of SHA-512 is that this would benefit an X25519-only based
implementation because that requires SHA-512 anyway.
