Why is the api-key data removed from the response of GET /admin/users/user.json?

Can i know why you remove the api-key data from response when we made a GET request to /admin/users/:user_id.json. I don’t remember since what version this value was removed from response, but it seems to me that it was available in the pass.
If I use a global admin API key that doesn’t affect the stats of the forum ?
If I use a global admin API key for my forum integrated mobile app, then what is the purpose of get or generate single user Api key ?

Thank you very much :+1:
