This is the module that infrastructure uses (and I wrote) to replace
use of limits on *

It was written after the last attack on our servers in which the
attackers uploaded CGI scripts;  We have some specific use cases where
we want to allow CGI in some places, but all of them have very limited
methods they should accept.  Trying to configure <Limit for our use
case and diverse set of vhosts would of meant duplicating the config
in hundreds of places.  I don't think the module is really great as an
alternative, but it is one path to consider, and is working for at
least one use case :)
