Hi, I have a question about the "DenyAddAndCustomizePages" setting.
The "learn" article does not say anything about this continuing to work for modern pages, though (only here in your note).

My question is, is it guaranteed this setting will continue working for modern pages always (Oct 2028 and beyond)? Or is it planned for this to stop working for every kind of page globally in SharePoint online at any time soon?

Regards.
