That's why it matters that it's also open source.

It's similar to Big-O notation, seeing that it's in Rust gives me an idea of performance profile to expect. If it's a Rails project I know that the best case scenario is fairly resource intensive, no matter how good the code is. If it's Rust then I know that for an average quality open source project it will be lower resource usage. If a project ends up being terribly inefficient after that, I'll drop it regardless of what stack it's in.

Knowing what tech stack something uses is a valuable first signal.
