Ah, sorry for the confusion :).

Well, it was the same token. I just reflashed it and then put different
keys on it.

FWIW, after removing them all,

  $ gpg-connect-agent "keyinfo --list" /bye

looks better.

Might those be private keys for which no public key exists?

Same here:

  $ ssh -Q key
  ssh-ed25519
  ssh-ed25519-cert-v01 at openssh.com
  ssh-rsa
  ssh-dss
  ecdsa-sha2-nistp256
  ecdsa-sha2-nistp384
  ecdsa-sha2-nistp521
  ssh-rsa-cert-v01 at openssh.com
  ssh-dss-cert-v01 at openssh.com
  ecdsa-sha2-nistp256-cert-v01 at openssh.com
  ecdsa-sha2-nistp384-cert-v01 at openssh.com
  ecdsa-sha2-nistp521-cert-v01 at openssh.com
  ssh-rsa-cert-v00 at openssh.com
  ssh-dss-cert-v00 at openssh.com

Also, keep in mind that everything except gnupg remains unchanged. If I
go back to 2.1.6, everything works again. If I update to anything newer,
SSH breaks.
