Displaying a warning to users doesn't make sites "inaccessible".

Sure it does. Users fear warnings they don't understand, and some will not click past they warning. For those users, you might as well replace the page with a 404 for all the good it does them. Maybe there are not MANY such users; I don't know and would love to find out. But surely some.
