Global Policy for Channel Edit and Delete Settings

I can't believe there is not a global policy for this setting. We create many New Teams a Month with members of multiple competency levels. Going into each Team individually and disabling the create, edit, delete options is not effective on multiple levels. As it stands, by default in Teams, any member can delete an entire channels worth of information in a single click. The only option around this is to go into every single team and change a setting which effects all users, including Owners. How is there a messaging policy for preventing users from editing and deleting messages, but not one for channels! 

Does anyone know if there are plans to add this option. I have read there is a powershell to disable all users. But this defeats the point of policies and add issues when other admins need to make changes in the future.
