Written in X can definitely be a value proposition.

If you are evaluating a tool/lib/etc that moves at a fast pace and your whole shop is extremely fluent in language X there's huge value add to being able to dive in without a context switch to understand how it works, especially when debugging harder problems.

I don't think it applies to _this_ case where we're getting a VM that is _extremely_ battle-tested. Am I going to use a new OS instead of linux in production because someone tried to write an OS in zig? No. Will I congratulate the author for writing an OS in zig? Yes.

If I am looking for a key-value store and two are equivalent in their purported features and stability, I will choose the one that is written in X that my shop is most fluent in.
