In the DevDocs, Magento details the possible
meta tag names available to include in the head layout XML. The explanation for the
media_type tag caught my eye:
This tag will not render (see \Magento\Framework\View\Page\Config\Renderer for details)
Indeed, when checking the class mentioned, it looks like the
media_type tag will not output anything:
case 'media_type': $metadataTemplate = false; break;
What is the reason for including this in both the documentation and in the code, if there is no output rendered?
