There's a use-case for more than a single approach. Margins and also collapsible margins are tremendously useful. In case of text of an article for example, where space changes based on other elements on the page (e. g. larger space above headings - the linked article also uses them).

In addition, if there's also CSS for `:first-child` that removes the leading margin and `:last-child` that removes the trailing, you can easily wrap them inside another component to remove the margins (or introduce a property to collapse them if you prefer). Of course, this is a bit more advanced and needs to be included in the documentation.
