Ideally yes. But right now, I don't want to take any risks and rather show an additional "please review the data carefully" message than risk one not being shown when it should be.
There is no harm in showing an additional warning message. There is a lot of potential harm of not showing it.
Indeed, trying to select many apps for batch uninstallation is very tedious and annoying in Geek Uninstaller. It's much easier with Uninstalr. Also, as a side note, the batch uninstallation feature is not even available in the free version of Geek Uninstaller, you need to buy the pro version to use that feature.
