For some use cases it would be beneficial to be able to use web api capability to directly return the created record using Xrm.WebApi.createRecord function. Web Api itself is capable of such behavior (https://docs.microsoft.com/en-us/powerapps/developer/data-platform/webapi/create-entity-web-api#create-with-data-returned) and it would be most useful if this could also be done with Xrm.WebApi.createRecord.
