Pros & Cons for storing Enumerations in Process Config or Database

When it is stored in Process Spec, Project admin is the only person to modify the enum. When it is stored in Db, we can grant edit rights to specific roles & remove the dependance of Project Admin.
Is there any other advantage in storing Enum in Db ?

We maintain the template in one project and share it with 14 other projects. Other 14 projects use the process config of "template" project. Process Sharing.

Pointers welcome.
