Hello,
When I create unattended key with cv25519 or ed25519 as subkeys, GnuPG
doesn't apply 'encrypt' usage, expire date and preferences. There is no
problem with RSA.
Regards.
(PS : My example key numbers were padded with X and Y)
$ gpg --batch --gen-key
Key-Type: ecdsa
Key-Curve: ed25519
Key-Usage: sign auth
Subkey-Type: ecdh
Subkey-Curve: cv25519
Subkey-Usage: encrypt
Passphrase:
Name-Real: Yan Fiz
Expire-Date: 1y
Preferences: twofish sha512 zlib
$ gpg --edit-key XXXXXXXXXXXXXXXX showpref quit
