I've discovered that when a plugin that provides templates that are compatible with a block theme (SenseiLMS, WooCommerce, LifterLMS confirmed) are present and a theme is exported from site editor the plugin provided templates are included in the downloaded theme.

I'd like to encourage a discussion regarding whether or not all plugin provided templates should be included in the export or only those that have been modified in the site editor.

My reason for bringing this up relates to the possibility that there could be a risk of templates becoming invalid or increase confusion if a theme is created and subsequently installed on a site when no actual modifications have been made to those plugin provided templates.
