I’m sorry to be that guy, I really am.
But I can’t help but wonder who the data export/import feature is meant for in this form?
Given that it’s only possible to use this via the CLI, it’s clearly aimed at developers.
But as developers you could have always exported and imported on SQL level already. So I don’t understand what new it brings and what the fuzz is about.
When I first heard export/import, I had assumed (my fault) that it is a feature for content editors. I don’t know, go into the content manager, select one content-type, select one or multiple entites of that content type and click a button to download an export of these entities. Go somewhere else and import these entities. Basically like this plugin, but natively.
I’m really sorry to be so negative. Am I missing something?
