Comment(by prettyboymp):

 To the arguments against the filter in #11312:

 The solution of setting $is_404 to false doesn't work since the handle_404
 function also checks post count.

 Adding a hook to template_redirect to override the 404 status header would
 also overwriting the no-cache headers that were set.  Which, I understand
 its a simple thing to override those too, but now you have several headers
 being messed with at different points in the program flow, which is just
 opening a bigger gap for conflicts.
