I hope it was a pleasant surprise, I found this from a data archivist perspective. I can't believe that only FLAC had the foresight to checksum large binary data in the media codec space. I notice that LLM releases will include md5/sha256 for the binary data, while excluding the json metadata. I really wanted MKV to have this functionality.
