Why does seeded General Accountant job role include access to the Setup and Maintenance

Summary:

We have used the seeded roles like General Accountant job role as recommended. However, a lot of these roles include access to the Setup and Maintenance and Configuration options which should not be given to an accountant using GL. Requesting the confirmation and rationale as to why these roles have been delivered this way. What is the difference between the Administrator role and the ones that are not, for example the Financial Application Administrator. If there is an administrator role why include the Setup and Maintenance in the other job roles?
Thank you so much for your help.
