Yes.  Here's the actual commit that implemented this all:
http://git.sv.gnu.org/gitweb/?p=autoconf.git;a=commitdiff;h=2d75db

Note in particular the addition of --enable-option-checking=fatal as a
./configure argument.  We can't make it fatal by default, because that
would violate GNU Coding Standards, but there is nothing that says that
you can't add a site.config file to make it fatal by default on your machine.
