Administrator requirement for repo default setting

My thoughts:

it is also a goal for me to have Allstar's default settings represent the highest level of security best practices that we (OpenSSF) can recommend. ...
That said, I also acknowledge that my point of view is from a large-org perspective, and while the org admins do have transient permissions on all repos, they can't be expected to be responsible for all repos, and a direct admin should be required. I see how this would not be the case for a small org. I'd like to bring this up at the next "Best Practices" WG meeting to discuss further.
