Will our customer still engage in licencing problems if we don't customize the Employee Role?

Around two years ago, Oracle started requesting all the partners and customers to be aware that the OOTB Employee Abstract Role had privileges from multiple offerings that made the role dangerous to provision without modifying it, specially for customers who only used Oracle Fusion CX Sales. If the role wasn't copied and some privileges and inherited roles were removed, the customer would have licencing issues.

I remember using this guide to perform the necessary tasks:

https://docs.oracle.com/en/cloud/saas/sales/oscus/remove-excess-privileges-from-the-custom-employee-role.html

Now the link is broken, and I just want clarification about whether it is or isn't necessary to modify the Employee Abstract (or any other role for that matter).
