- Supporting SQL and non-SQL indexes on the same field - they must work equally.
- Rebuild, clear, defragmentation tasks, control.sh, system views, IndexRowCache, security checks, etc(?) for non-SQL indexes - all of the tooling should work correctly with non-SQL indexes.
- Need support for tracking index queries (security checks, tracing, query views).
- Transactional support for "update for select" should be discovered.
- There can be performance issues with IndexFieldsOnly queries due to reflection, or wrong inlining.
