If someone really misses functionality, we should fix that deficiency in hw/xfree86, xf86-video-dummy, or xf86-video-nested.  Also, there's nothing stopping anyone from using older server versions if they still need these DDXs.

Nice try, but did you read that commit?

   if (!strcmp(argv[i], "-config") || !strcmp(argv[i], "-xf86config"))
-    if (getuid() != 0 && !xf86PathIsSafe(argv[i + 1])) {
+    if (xf86PrivsElevated() && !xf86PathIsSafe(argv[i + 1])) {
       FatalError("\nInvalid argument for %s\n"
-         "\tFor non-root users, the file specified with %s must be\n"
+         "\tWith elevated privileges, the file specified with %s must be\n"

It will still FatalError if you attempt to pass a -config path when the server
is installed setuid, as it currently must be to support actual hardware
