In practical usage, as Tupka says, there is no need to sign or timestamp deletion requests. What delete templates do is place the article into a category:delete (or :speedy deletion, etc). When a mod or admin comes along to clear out the items in these categories, we just mass-delete everything until it's empty. Most often we use macros or scripts and set them running while we perform other chores.

So really, not a need.
