Re: Databricks announced the full open source of Delta
Your statement on Zorder isn't true... it's not a clumsy implementation, it's the multi dimensional one (https://github.com/delta-io/delta/issues/1134) that is good enough for mostly use cases.
Your pretty detailed example against Databricks is also true if a customer start using Iceberg in Snowflake proprietary version of Iceberg bits, optimizations etc will be there but it is not open sourced. I don't follow your purism also, Iceberg has a company behind it that pretty soon will have their benefits only in their cloud (if doesn't have it already since I'm not following them directly).
