Modern Library "Notify your team" option after upload - with uncontrollable or auditable results

Much like the "Request Sign-Off" Flow, not being able to manage if these options are active/available is problematic for us. We were not even aware of the feature (note: a FULL search of the MS Roadmap did not mention it) and poof there it is, and so I wasn't able to get ahead of it and warn people about what it would do. Execs were emailed 3 documents they did not need to be bothered with. And as I could not reach the person using the feature by phone right away, my only option was to remove his access so he wouldn't send anymore out before I could talk to him about it.
