Seems like this is going to be a permanent issue, no? Library level storage APIs are complex and often quite leaky. That's based on looking at the innards of MySQL and ClickHouse for a while.

It seems quite possible that there will be maybe three libraries that can write to Iceberg (Java, Python, Rust, maybe Golang), while the rest at best will offer read access only. And those language choices will condition and be conditioned by the languages that developers use to write applications that manage Iceberg data.
