Why model service still using fetchAll?

Also would you please help guide how to set default value for strapi 3.6.2?

How can I set "default value" to blank?

I need set some string field’s defalut value to “”, but I can’t set it via admin tool. So I add "default": "" line to model.setting.json manually like this: "name": { "type": "string", "default": "" }, But if I edit model.setting.json(such as add a new field, or adjust some field setting). then the "default": "" was removed from model.setting.json. My question is can I keep "default": "" in setting.json file?

System Information

Strapi Version: 3.6.2 Operating System: macOS Big Sur Data…

Or best practice for set a default value? Because we have other legacy applications need all fields from strapi model, if fields not exist or null, other applications will be broken.
