This is a limitation of our ssh_config parser. Sadly, libssh2 doesn’t support ssh_config parsing, so we had to write our own. AFAIK, libssh does support ssh_config parsing, but I don’t know if this would solve your particular problem and it’s a big effort to migrate.

The following options are not supported by our parser:

  * PubkeyAcceptedKeyTypes
  * HostKeyAlgorithms
  * KexAlgorithms

You can improve it (or migrate it to libssh?), or else upgrade to a more secure system :)
