As long as you don't see any dependency errors, it is safe to uninstall the unmanaged package

Hi Anudeep, 

Thanks your reply. I still have a question about it.

As above question, I create a Lightning Component Tab in Salesforce Setup Tabs. And this Tab's component is the lightning component in unmanaged package.

After this unmanaged package uninstalled. This Lightning Component Tab still existed. When I navigation to this Tab it show empty page.

May I ask is this phenomenon correct？ Is here anyway can deleted this tab during uninstall this unmanaged package?
