Should eventParticipant in Adverse Event be a collection (cardinality 0..*)?

In going through the model definition for Adverse Event, I noticed that the cardinality for eventParticipant is 0…1, and it is either a Practitioner or a Device. Would there ever be a need for more than one eventParticipant, whether both a practitioner and device, or multiple practitioners? This is a new space to me, so I’m just trying to understand normal use here.

In the current build, it’s been renamed “contributor” and is now 0…*
