The lack of ability to add new fields to a webhook event workflow trigger makes any update require:

1. Mapping a new webhook URL in other tool
2. Remapping all webhook keys to event properties/fields, not just the new ones needed (very time consuming with many-property events)
3. Remapping all workflow functionality to the new event properties
4. Losing historic event completion data from the now obsolete event
