My point had nothing to do with languages. My point is against rewrites of critical software for the point of rewriting it *insert my favorite language*. Zig is also a safer language than C, so are many other alternatives, yet the Zig community is not obsessed in rewriting old software but writing new one. And the Zig compiler has excellent C interop (in fact it can compile C/C++), yet the community is more focused in writing new software. There are many factors that make software reliable, it's not just a matter of pretty types and memory safety, there's factors like platform/language stability, skill and expertise of the authors, development speed and feedback. |

In this specific case we are talking about the maintainer adding a new language into the existing codebase.
I think refactoring parts of the software in the new language is what you call "rewrite" here, correct?
So what improvements does it bring? You actually answered it yourself:
> it's not just a matter of pretty types and memory safety
So indeed, stricter/stronger type system and additional automatic compile time and runtime checks are a major improvement.
> platform
As already mentioned in this thread: neither of the platforms lacking Rust were supported officially anyways.
> language stability
Rust is extremely stable and backwards compatible - 1.0 code still compiles without any issues on 1.90 and will continue to do so for the forseeable future.
> skill and expertise of the authors
The same developers continuing to contribute and newcoming developers have more checks in place to prevent bugs.
> development speed
I guess you imply here that developing in C++ is faster. It's in fact not if your aim is to produce correct software. There are so many more things to keep in mind and take care of with C++, you have fewer automatic checks being done by the compiler and the type system.
About Zig: it's a nice language and much more comfortable to use than C/C++ IMO, but compared to Rust it lacks in strictness and safety, so added benefits are smaller and fewer if you put away subjective preferences.
