Hi Mike,
SharePoint has made some changes on that, currently, we will not get notifications when sharing documents by our own because we already known that.
If you would like to know the access permission of documents and files, you can easily go to the Documents library information panel and hit Manage access.
Meanwhile, if you have any suggestions, we suggest you submit your feedback at SharePoint USerVoice.
Regards,
William
