Description
The existence of these carveouts suggest that we will error if we try to query with indices we don't support:
There are some properties we should validate in tests:
If a dataset contains an unsupported index:
- We can still scan and query the dataset
- We can still write to the dataset, and it will preserve the unsupported index
- We can still run optimize indices, and it will preserve the unsupported index
- We can drop the unsupported index

Research direction
Start with python/python/tests/forward_compat/test_compat.py, especially the linked carveout, and trace the dataset operations it exercises. Add coverage for scanning, querying, writing, optimize indices, and dropping a dataset containing an unsupported index; done means all five operations work and the index is preserved except when dropped.
