Marked as Implemented. In Alpha 3, the following behavior occurs:
- When most pages have no text content or show placeholder text, no contributors are displayed; however, attachment pages still show contributors responsible for the upload, regardless of whether text was entered.
- Only show Views if contributors are being displayed.
- When a container (areas, books, etc) has no text content, check the value of "Settings > Wiki: Aesthetics > Show Placeholder Text on Wiki Containers" before showing placeholder text.
- The first block will not render if it follows these rules and ends up with no contents at all. However, other elements in that block, such as categories, likes/reactions, etc should be unaffected by the change and would still cause the block to render if they render. Keep in mind that there is no minimum height on these elements so that should not be an issue.
This combination is working well in my tests in XenForo 2. Since it did not require major template changes, it should also work well on other platforms.
