I've copied my comments from GitHub here for a broader discussion:
Hi, I have two concerns about this change: • `.gz.metadata.json` is quite uncommon and can't be read by most existing tools. Would it be better to support `.metadata.json.gz` and treat `.gz.metadata.json` as legacy for backward compatibility? • `gzip` is becoming increasingly outdated due to its lack of support for modern CPUs. New algorithms like `zstd` are gaining popularity, so should we consider allowing users to use `.metadata.json.zst` as well?
