The main feedback around this seems to be to speed up response times in the export process. There will be some improvement on this front in the next version.
As far as skipping data goes, I think this feature would cause some confusion to a majority of users. It would be better to focus on enhancing the export process instead.
I see your point about confusing people. I don’t mind if it still does the check for data on the server but as long as it’s super fast. It’s not a big deal if you’re exporting a few weeks of data. But when you’re exporting years of data, it becomes painfully slow to do, especially if you already have all the data stored locally.
