Many projects hide the heading on the main page on Vector.
They often do this using an !important rule inside MediaWiki:Vector.css
It's proposed we provide an HTML based approach to doing that, by allowing editors to blank the page.
Currently blanking the page, disables a message, and when disabled
Given the changes in T255682 we could make it adapt this to make it possible to do this without the CSS changes.
The main page title is now controlled by a message mainpage-title.
- Editors can blank the associated message to remove the heading on both Vector and Minerva (needs changes in Vector and Minerva for this to work).
- The title attribute is not impacted by the change
