Q: Isn't the "Role Based Access Administrator"-role enough?

[Salazander]

Hi
We are working with a customer who takes the "principle of least privilege" very seriously.
The Root Service Principal requires a privileged role to function properly, the "User Access Administrator" role according to the docs.

For which use case of the Azure Secrets Engine is the "Role based access administrator" role insufficient? We have been using it successfully for a while now and I was wondering what feature we are missing out on when not using the more privileged "User Access Administrator" role.

Thanks for any insights!
