nistp256 preferred over ed25519

[Fedor Brunner]

Hello,
Maybe I'm asking an already answered question, if yes I'm sorry to
bother you.

Why in default HostKeyAlgorithms settings is
ecdsa-sha2-nistp256-cert-v01 at openssh.com preferred over
ssh-ed25519-cert-v01 at openssh.com ?

For example in default settings for KexAlgorithms the
curve25519-sha256 at libssh.org is preferred over ecdh-sha2-nistp256.
