I'm trying to find a garage door opener that automatically closes

the only thing I'm finding is an aftermarket 'butler' that works
wirelessly, which is fine, but do any openers have this built in?

I've never seen one and seriously doubt that any opener manufacturer
would offer such a thing because of the obvious liability issues with
unattended closing.
