Microsoft’s new SharePoint architecture model means that the all governance plans need to be rewritten. Modern cloud features are nowhere near the same animal as on-premise classic SharePoint.
Everything is now a site collection and suddenly subsites are a swear word, (pretty much like subfolders were back in the day). The site collection model is more flexible so you can change the hierarchy when the company changes and attach them to hubs. Microsoft Teams, the Add New Site from SharePoint and Planner all make new site collections though, and instantly lock out the SharePoint Admins. You need PowerShell scripts to get access to all site collections.
One way to stay ahead of the game if you don’t have a PowerShell person nearby, is to put an alert on for yourself on any new site collections created.
Go to the Security and Compliance Centre in Office 365, then the Records Dashboard and Alerts.
There are some default alerts – you can get alerts on multiple actions :

When you’ve configured your alert, you can see all it’s settings by clicking on it.
When a user creates a new site collection, you get an email.
You can view alert details and filter on data to get to specific results.
Access the link to the site created by clicking the alert, then View Activity List.
Double click the URL and paste into into a new window to access it.
Then you can action the alert if the site is all okay.
Use the filters from the View Alerts screen to view all alerts.
