Renamed flavor pages are not updated by the DW

Hi! Yes, indeed there is a warning, but the warning is fairly easy to ignore and pass over. Not all UI XWiki Admin are advanced, or understand this warning consequence.
This not only that could break those extensions, but leave them outdated putting them at risk for fixed and published security issues. 
For previous situations I encountered many instances where the Main space was renamed. They mostly have been renamed because they wanted a different homepage, which is not the right way to achieve this.

What I would want indeed could be classified an improvement for security hardening:
Deny rename for these pages, only superadmin to be able to rename them.
