I am wondering if it is safe to manually remove entries on the db_schema_whitelist.json file. I created a table called customer_address_relationshipusing the declarative schema approach and then I generated the db_schema_whitelist.json first and ran the php bin/magento setup:upgrade command. The generated db_schema_whitelist.json file had the following entries:

{
    "customer_address_relationship": {
        "column": {
            "entity_id": true,
            "customer_id": true,
            "address_id": true
        },
        "constraint": {
            "PRIMARY": true,
            "CSTR_ADDR_RELATIONSHIP_CSTR_ID_CSTR_ENTT_ENTT_ID": true,
            "CSTR_ADDR_RELATIONSHIP_ADDR_ID_CSTR_ADDR_ENTT_ENTT_ID": true
        }
    }
}

I then later decided to change my approach to the problem at hand and had to drop the customer_address_relationship table (by removing it from db_schema.xml and generating db_schema_whitelist.json again and then running setup:upgrade). The better approach was to add a column instead to an existing table called customer_address_entity after adding the column in my db_schema.xml and generating the db_schema_whitelist.json file the content of the file was now as follows:

{
    "customer_address_relationship": {
        "column": {
            "entity_id": true,
            "customer_id": true,
            "address_id": true
        },
        "constraint": {
            "PRIMARY": true,
            "CSTR_ADDR_RELATIONSHIP_CSTR_ID_CSTR_ENTT_ENTT_ID": true,
            "CSTR_ADDR_RELATIONSHIP_ADDR_ID_CSTR_ADDR_ENTT_ENTT_ID": true
        }
    },
    "customer_address_entity": {
        "column": {
            "address_type": true
        }
    }
}

Since I no longer need the table customer_address_relationship is it safe to alter the generated db_schema_whitelist.json and remove its entries? what is the implication of this if there is any?
