This is only used in tests as far as I can tell, what is this for?

Good catch — this helper was only used by the test. I removed it and the test, and cleaned up a couple of nearby compression-only leftovers.

That is adding quite a lot of bytes on your compressed data.
Keeping the config in the compressed payload is necessary as we saw in the other PR to allow any consumer to decode the payload, but we should find a better encoding mechanism than base64 which is inflating the final payload size.

Agreed. I moved the compression config into encoding_metadata and now keep the compressed bytes directly as the payload, so we avoid the JSON/base64 envelope overhead while preserving config-independent decoding.
