Child theme necessary?

Dear Woocommerce team,

so far I’ve used a Divi-Child theme to make small changes to style.css and functions.php. However, I have now switched to a code snippets plugin and therefore want to delete the child theme and work directly with the parent theme.

When looking through the corresponding FTP folder, I noticed that Woocommerce and the plugin Woocommerce Germanized have each created a folder with several email templates in the child theme. These look like this: https://we.tl/t-u5TUFdaeue Can I just copy them to the folder of the parent theme or do they need a child theme?

Best, Kurt
