Slackware for one:

2nd release for v13

probably because that is the default for openssh, at least for version 5.1p1,
of course that is no excuse

see sshd_config:
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.
