People have tried: https://github.com/jkcfg/jk
But yeah I agree. The thing is, if all you need is robust determinism why do you need a full functional language with currying and other complex concepts?
Google had the same problem for Bazel, and their solution (Starlark) is way easier to understand.

If I were writing a build system today (and I did just write one actually to test out some ideas) I would use Typescript for the language with something like jk to provide hermeticity. Typescript has many advantages, especially over Python, but mainly:
The Perfect Configuration Format? Try TypeScript
Great little writeup ! After mangling YAML, HCL, JSON for years as an ops engineer, I have come to the same realisation. In fact, I have put this into practice in production pipelines by using: jkcfg for the last couple of years. Two data points: 1. Zero developer support contract rate around YAML syntax and templating issues 2. High number of contributions in our private typescript configuration library from developers. Using typescript as an ops frontend has made operations a lot more approachable to folks.
Recently I took what learnt in the last 2 years using jkcfg/typescript and taken it to Deno in form of an opinionated port of jkcfg called: dxcfg. Its early days, but I would bet on Deno/typescript for future ops configuration.
It's possible to sandbox most languages, and with some work you can probably make them deterministic too.
Here's an example: https://github.com/jkcfg/jk
That beats having to learn an entirely new language.
Why? The only reasons I can think of are:
* They can be non-deterministic (do a different thing each time you run them).
* They can be non-hermetic (access stuff in the environment you don't know about).
* They can do naughty security things.
* You can't present GUIs of them because they aren't declarative.
For the sorts of places where you don't have a GUI for the settings anyway (which is the common case) I think it makes loads of sense. It beats making the kind of declarative programming languages you see in YAML files.

You may be interested in jk. If you don't want to use a special purpose configuration language (jsonnet, cue, dhall, etc), this is a nice alternative that uses js in a hermetic runtime (but see their open issues for progress on that). They seem to also be adding native typescript support so you could even have type checking built-in.
