How can I undo an import on most platforms?

Can someone point me in the right direction to learn how to undo an import? In most platforms this is typically called “rollback” of an import, but for some reason I can’t seem to track down a single help article about how to do this.

I read somewhere there’s no way to rollback an import.

I can’t figure out how to delete this post…Is there a delete button that anyone has found in here?

Also…wtf, why wouldn’t Shopify allow import rollbacks? Most platforms allow this. Very strange.
