I increased this to 4MB when I implemented abort-on-stack-overflow for Rust functions. Now that the fixed_stack_segment attribute is removed, no rust function will ever reasonably request 2MB of stack (due to calling an FFI function). The default size of 2MB should be plenty for everyday use-cases, and tasks can still request more stack via the spawning API.
