This would work in tandem with the suggestion to have multiple workspaces in port (i.e. orgs could have a stage and prod version of port). Essentially, instead of data exporters only sending data to one instance of port - this would allow us to configure exporters / webhooks to send the data to multiple port organizations.
The value is that then data can be mirrored easier between stage and production and testing with the data in lowers is more reliable because you have real data to work with.
