Surprised and happy to see this. Made an account just to comment.

Just last week I was looking for similar functionality in Cloudflare as I am exploring publicly exposing apps I have built (as opposed to just me and some friends on a home lab).

My main concern on public cloud platforms is costs. I never want to spend more than, say, 10 EUR on a simple service. In my mental risk matrix, the chance of a cost-related issue has been increasing more-and-more. I am creating and hosting more than ever, and the chances of malicious activity/abuse are in my opinion higher than ever before.

It feels like cloud providers either are unaware of this, or riding a wave of increased turnover - which I think a more likely.
