Configuration access control

Would it be possible to add a permission for the access control to the settings page for og_user_roles?

On our sites we have a number of roles, two of which are capable of accessing the administration pages (i.e have 'administer site configuration' permission). We don't however want them to have access to the og_user_roles pages as they don't have access to Roles or Access control (i.e don't have 'administer access control' permission). I've fixed this problem temporarily by giving the administration menu item 'administer access control' permission, however, I'd prefer it if this were either made permanent, or given its own permission so we could fully control who can access the og_user_roles admin menu.
