What did you see instead?

Additional notes
Although the README still refers to that experimental feature, Pull Request #2393 removed it from the code base1. There was no conversation about that removal in the Pull Request. The exporter-toolkit was updated, but it seems that the new version still supports that feature. Was there a discussion to remove that experimental feature which I am missing?
