> Clojurescript for frontend, Rust for portability
If Clojure and Rust work well for you, more power to you. But at least in theory, you could very well use just Scala for these purposes
Scala can compile to JS https://www.scala-js.org/ if you target frontend.
And if you want portability, you can compile a Scala program with GraalVM's native-image and statically link everything with musl libc https://www.graalvm.org/latest/reference-manual/native-image...
And if you want both frontend and portability everywhere, Scala will soon have a support for compiling to WASM (with WASI, etc) https://github.com/scala-wasm/scala-wasm/ (to be integrated into Scala.js after developed)

Vale is interesting, https://vale.dev/
For memory safety compared with Rust it does not use a borrow checker for the price of more checks and extra memory usage at runtime while avoiding GC or even reference counting.
I think this is very interesting trade off. Plus there are plans to implement few interesting ideas that even Rust type system cannot implement while keeping the language simple.
