In order to keep the data up-to-date between our system and the Adobe Acrobat Sign API we want to allow the change of a participant's name without also having to change their name.
The current behavior of the API can be found here:

}

The API detects that there is no change in the participant hence ignores any changes in the memberInfos name property. It would be very welcome to be able to change the name only for our use case.
We had a call with Adobe support regarding this very issue and were asked to submit a change request for it.
