Research direction

This is a meta tracking issue for adding React 16 support to Enzyme. It contains many sub tasks, most of which are already completed. A newcomer should not work on this issue directly but instead pick a specific open sub task like 'contextType' (linked to #2189) or 'StrictMode'. Investigate the linked issues and PRs to understand current blockers and implementation details. The assignee may already be working on it, so engaging in the relevant sub issue is recommended.
