I've done a binary representation of JSON-structured data that uses unary coding for variable length length fields: https://github.com/kstenerud/bonjson/blob/main/bonjson.md#le...

This tends to confuse generic compressors, even though the sub-byte data itself usually clusters around the smaller lengths for most data and thus can be quite repetitive (plus it's super efficient to encode/decode). Could this be described such that OpenZL can capitalize on it?
