The status variable is not dead, it's updated when JSON functions are used:
MariaDB [test]> select json_valid(1); |
+---------------+ |
| json_valid(1) |
|
+---------------+ |
| 1 |

1 row in set (0.000 sec) |

The variable is defined in the documentation as
Number of times JSON functionality has been used, such as one of the JSON functions
JSON_TABLE definitely counts as "JSON functionality".
