It's a really interesting idea! I'm also surprised there hasn't been much traction here. I've started a Rust library for this: https://github.com/sharksforarms/deku

It's a declarative bit-level symmetrical reader writer generator library.

I have been working on Deku: a declarative binary reading and writing: bit-level, symmetric, serialization/deserialization library. https://github.com/sharksforarms/deku
