I started adding a column to https://docs.google.com/spreadsheets/d/1r-IjEyTEuCzQtJgSyY-a5htrQFME9RPylkv3hT_puqg/edit?gid=1971388798#gid=1971388798 called "Context available at async dispatch", which marks for events dispatched asynchronously which async context would be trivially available.

This shows for how many events it would be easy to add a .dispatchContext property / how easy it would be to use the dispatch context rather than the registration context. All events that can be triggered by JS and have no "available context", or have the wrong one, will need manual wiring.
