This is a very different thing. Deno deploy have identified a few commonly used tools and implemented them as (IMO) very leakless abstractions. Why hire a team of engineers to implement a worse abstraction layer for you? Performance (in particular cold start time) is better than most other similar cloud faas products. Dev ergonomics also. If you need something more, sure go ahead and use another tool. But very many use cases will be well served by deploy in its current state.
