Restrict Network Templates

Restrict the management of templates to a network's main site.

Description

This plugin should be network activated on a multisite network. When activated:

• The list of default template types is filtered to return an empty list.
• The /wp/v2/templates endpoint in WordPress returns an empty list.
• The WP_REST_Templates_Controller permissions check is overridden to prevent the update of templates outside of the main site.

This plugin works in tandem with Network Template Parts to provide a framework for a shared look and feel of websites on a multisite network.

Activating this plugin will impact the usefulness of the full site editor in WordPress and will require thinking about the site in parts rather than full templates.
