Hi. Please take a look for example at this page history. Every time the template is amended via Special:CentralNoticeBanners CentralNotice issues a new protection to the page. This is unnecesary and unnecessarily pollutes the page history and the protection log. Please have CentralNotice check if the page is protected and its settings before issuing a new protection
In the long term I suggest a dedicated namespace for CentralNotice stuff, protected by default (via $wgNamespaceRestrictions) to the desired levels. Issuing indefinite protections cause Special:ProtectedPages to become increasingly long as well, making it difficult to patrol.
Thank you.
