Review and eliminate iceberg dependency group

Title: Evaluate necessity of iceberg dependency group

Labels: dependencies, investigation, cleanup, breaking-change

Description:
We need to assess whether the iceberg dependency group is still necessary or if it can be removed/consolidated with other groups.

Background

Dependency groups should be minimal and user-focused. If the iceberg group isn't providing clear value or is rarely used, it should be removed or merged with other groups.

Tasks

• Audit usage of iceberg-related functionality
• Review download/usage statistics for iceberg group (if available)
• Identify which features depend on iceberg dependencies
• Evaluate consolidation opportunities with other groups
• Plan migration path if removal is decided
• Update documentation and examples

Acceptance Criteria

• Clear decision on iceberg group fate with rationale
• Migration plan for existing users (if removal)
• Updated documentation
• No broken functionality for legitimate use cases
