PyIceberg Production Use case survey

### Feature Request / Improvement

As part of the journey toward version 1.0, we want to capture how this library is used in "production" environments.

Would love to hear from current users (and potential users) on different use cases. This will better inform the future roadmap.

Please include use cases in this issue, or if necessary I can start a Google Survey.

從 issue 討論開始，檢視現有的 15 則留言，以了解 production 和潛在使用者的使用情境。未指定任何檔案或測試；完成的標準是在 issue 中收集具代表性的 PyIceberg production 使用資訊，或建立並使用提議的 Google Survey，為未來的 roadmap 提供資訊。
