in a perfect world yes, even more than 75%

in reality: only *the one an donly* case which affects me untila update is released
we need the > 75% because we don't know what is needed when

but even if we reach only 25% it's better than 0% by giving up and drop the firewall

it makes me really sad that anybody ever can come to an idea disable the
