The start_event and end_event keys are useful for explaining why a feature has a particular start_date or end_date out of several possibilities. From a data consumer standpoint, it is also a more predictable alternative to note and description. iD should offer Start Event and End Event as optional additional fields for every preset. It would be a multiline text field like note and description. The other keys in this table can be flagged as deprecated in favor of start_event and end_event.
