#3064854: Allow Twig templates to use front matter for metadata support → introduced the ability for templates to provide metadata using front matter.
This can potentially allow plugin managers that associate plugin definitions with templates (examples: layouts, help_topics) to inline the plugin definition with the template itself. Otherwise, you would need to put definitions into separate files and discover them using YamlDiscovery.
Introduce a new TemplateDiscovery abstract class that can be extended to discover plugins from Twig templates.
Use the template filename as the plugin ID, and allow extending classes to define what to do with extracted FrontMatter metadata.

It is used to alert the maintainer(s) of a particular core subsystem that an issue significantly impacts their subsystem, and their signoff is needed (see the governance policy draft for more information). Also, if you use this tag, make sure the issue component is set to the correct subsystem. If an issue significantly impacts more than one subsystem, use needs framework manager review instead.
The change is currently missing an automated test that fails when run with the original code, and succeeds when the bug has been fixed.
