So I know you delete the latest deployment to effectively pause it. But this has been a common topic for over 3 years. And it is really simple to implement if you already have serverless functions.

So why not enhance the user experience to allow them to pause instead of deleting a deployment. (You can specify max instances to 0, block incomming requests - so serverless stays sleeping, force sleep, run a script to remove the deployment). There are so many options to implement this feature. It really does come down to the small things.
