 yep, see src/bin/ps.c:
 305                 if (stat(ttypath, &sb) == -1)
 306                     err(1, "%s", ttypath);
 307                 if (!S_ISCHR(sb.st_mode))
 308                     errx(1, "%s: not a terminal", ttypath);
 309                 flag = sb.st_rdev;
 
 If you wouldn't fail now, you would fail later when you kvm_getproc2(3)
 without the device number.
