Zig is actually perfect for production network services (that’s all TB is essentially, or how I see it, and what I was looking for in Zig—how to create something with explicit limits that can handle overload—it’s hard to build anything production-grade if it’s not doing NASA’s Power of Ten and getting allocation right—GC is not a good idea for a network service).

I wouldn’t say Zig’s std lib is immature. Or if anything, it has higher quality than most std libs. For example, the unmanaged hashmap interface is :chefskiss. In comparison, many std libs are yet to get non-global allocators or static allocation or I/O right.
