Now that main can be suspended in 1.3, I propose an all-suspend plugin that would make all functions suspend functions (along the same lines of the all-open plugin), allowing a Go style of programming without having to mark each function as suspended.

(Note: I know next to nothing about Go, so I could be way off in my comparison. I'm also not sure of the implications of this idea, so I haven't even decided if I like it myself, but I figured I'd throw it out there.)

Then, you lose atomicity when you need to update multiple things in a row. Go is different in this regard as you have to write go to go asynchronous. In Kotlin, you can't use a suspend function in a non suspending way to make it synchronous. So this will very likely be never implemented in Kotlin.

What is real use case of that?

This would be awesome, though I'm pretty sure it would destroy the interoperability with the JVM. suspend is (as far as I can tell) logically equivalent to blocking, it's just that one is more efficient than the other. In multi-threaded programs, there is no such thing as atomicity without locking anyways.
