Hmm my reasoning was that in order to have Nginx work in Rust you want to expose scripting so having a decent Lua in Rust is key to not call out to C for that. And then Valkey/ Redis is a lot simpler than nginx so it was a good way to learn how some of this works.

And I'd disagree on no one wants - Lua is quite helpful since it is easily used in WASM. There has been some interest from people in the Bevy community - a game engine in Rust - since you can't have Lua scripting in browser games easily with the C version.

But anyway if people want it or not memory safety might become much more important so I think it is a good area to explore. Some people think large C codebases are inherently unsecurable https://alexgaynor.net/2020/may/27/science-on-memory-unsafet...
