Thanks for mentioning this, Dave.
As a first step, if you change the template from {{French Roots}} to {{French Roots Project}}, the Project account will automatically be added as manager at some point. This will add a protection since the profile will be more closely monitored.
Now about PPP which is another level of protection, to add this we'd need evidence that the profile is controversial or is likely to "lose" its Last name at birth through a bad merge.
If there have been issues (I'm not familiar with this profile or this person's history, unfortunately), we will certainly add project protection.
