There is now a MoodleDoc page for MoodleDocs:Templates which shows all the yellow banner type templates. I noticed the link on that page to: All pages (Template namespace) which has a full list of templates used in Moodle Docs.
And she added a new Category: Pages requiring a review . I like this because it puts it at the bottom of the page, and does not create a caution banner.
And yes Template fans, I will try to refrain from (transferring my pet peeve at wikipedia by) adding "appropriate use and placement" remarks to each of those yellow banners on the new page. MoodleDocs is much more civilized than 'pedia.
