Out of curiosity, what is the reason for the self-signature and subkey
binding signature continuing to default to SHA256 (digest algo 8)?

I made a test key by "gpg --no-options --quick-gen-key Test20171223".

Showpref gave me:-

     Cipher: AES256, AES192, AES, 3DES
     Digest: SHA512, SHA384, SHA256, SHA224, SHA1
     Compression: ZLIB, BZIP2, ZIP, Uncompressed
     Features: MDC, Keyserver no-modify
