It isn't reasonable to insist on this as an absolute policy.  If this
policy were strictly adhered to, most of the changes to config.guess
would be disallowed, as config.guess typically outputs something wrong
on unusual hosts.

People make mistakes.  Systems change.  The output of config.guess has
changed in the past, and it will change in the future.  The very name
"config.guess" suggests that its output should not be considered to be
unchanging truth.
