JSON_MERGE_PATCH does not preserve members with duplicate keys. It doesn't give you quite what you said you wanted, but may be helpful for what you're trying to achieve:

SELECT JSON_MERGE_PATCH(@json1,@json2);
+----------------------------------------------------------------------------+
| JSON_MERGE_PATCH(@json1,@json2)                                            |
+----------------------------------------------------------------------------+
| {"ccmilestones": "10701", "descriptions": "10702,10703", "lolo": "lolita"} |
+----------------------------------------------------------------------------+
