The following sqlite3 features were deprecated in Python 3.10, and are scheduled for removal in Python 3.12:

• sqlite3.OptimizedUnicode: bpo-42264: Deprecate sqlite3.OptimizedUnicode #23163
• sqlite3.enable_shared_cache: bpo-24464: Deprecate sqlite3.enable_shared_cache #24008

3.12 development was just opened, so these features can now be removed.
