That seems like it would require changing a lot of code. Calling it "production ready" is dishonest at best
If by production-ready you mean you can forever avoid changing code you wrote 8 months ago, sure, pick something else.
To me production-ready means it can be trusted to power production workloads, has all tooling I need, and has a consistent long-term vision. Zig ticks all the boxes.
