That’s a solid roadmap. Moving towards span-based management is progress, but the real challenge for any new language is achieving true Zero-Cost Abstractions.

In my work with Modern C++, I've come to realize that predictability isn't the result of a single feature like a scavenger or an allocator. It’s the cumulative integrity of every primitive—from a simple string to complex containers—all meticulously engineered to ensure the developer never pays a 'runtime tax' for what they don't use.

A great example of this rigor is why we still don't have Reflection in the standard: the committee refuses to compromise until a solution exists that adds zero overhead at runtime.

For Nature to truly bridge the gap, it shouldn't just aim for 'high performance,' but for that level of uncompromising zero-cost integrity. When the language's abstractions are so refined that the runtime effectively disappears, you reach a state where system behavior becomes perfectly deterministic. That is the standard C++ has set for decades.
