--confhost doesn't open any IdentityFile(s)

It seems that --confhost isn't opening any keys:

% grep IdentityFile ~/.ssh/config
  IdentityFile ~/.ssh/id_android
  IdentityFile ~/.ssh/id_boxy_rsa
  # IdentityFile ~/.ssh/id_4096rsa_20kdf
  # IdentityFile ~/.ssh/id_4096_jvlk.me
% keychain -k all --quiet ; eval $(keychain --eval --agents ssh --confhost); ssh-add -l

 * keychain 2.8.5 ~ http://www.funtoo.org
 * Starting ssh-agent...

The agent has no identities.

strace shows that no attempt is made to open the IdentityFiles:
