It seems to me that the correct definition of exists() in terms of
status() is just !(status() & not_found_flag).
The expectation with not_found_flag is that, assuming the branch() if
any is found, it should be possible to create a file or directory
with that path. Consider:
if (!exists("foo"))
     create_directory("foo");  // surprise! This may fail: "exists
but not a directory"
!exists("foo") == !!(status("foo") & not_found_flag) == status("foo") & 
not_found_flag

if( status("foo") & not_found_flag )
{
    create_directory( "foo" );
}

I don't see your point, but I may be missing something.
