@rfontanarosa or @gino-m can you provide some info on what this is needed for, in order to set the appropriate priority and milestone?

v2 Cloud Functions provide better performance and additional capabilities. Also, having everything in one version would help maintenance since we'd only code to one set of docs / APIs. I voted for P1 for Post-GA. See more here:
