This option has been deprecated in OpenSSH for nearly two years, was the default for five years before that, and is not part of the current Fedora default configuration. It should not be included in sshd_config on Fedora systems.
Currently only supported Fedora distributions are 22 and 23, and they both ship openssh 7.1p1 which supports all 'rsa', 'ecdsa' and 'ed25519' keys, turn them on by default.
Based on RedHat 7 with few modifications (ed25519 hostkey for F22,
GSSAPICleanupCredentials defaults to no, s/LC_TYPE/LC_CTYPE/ in
AcceptEnv).
Tested on Fedora 20 & 22.
