Tenant-wide policy to disable "Allow everyone in your company to view this video"

There is a setting to restrict users to create companywide channels and that's fine. But while uploading videos, users can still share their videos companywide. 

I think, while enabling "Restrict companywide channel creation" setting,  it should also restrict users to share their videos companywide. But that's not the case. It would be good to have:

1. A tenant wide setting to restrict users to share their videos companywide

or

2. While enabling "restrict companywide channel creation" it should also restrict users to share their videos companywide. 

Cheers,
