We expect this to be fixed now, and you should not need to request permissions unless you want to. The appropriate person to discuss that with is your contact from when you set up your Ads API access.
Generally READ-WRITE permission is all about optimizing campaigns and creative at scale and with efficiency, and a backbone of why we have an API, so there’s nothing stopping you from proposing a tool which needs WRITE access but it’s something you would need to discuss with the program manager contacts.
Thanks,
