Shoult Delete Company Data feature also delete Departments

ERPNext
#1

I did a reset of my test instance by deleting all company data. I noticed that departments also were deleted. Is this the intended behavior? Since departments are not transactional data maybe they should not be deleted.
Interestingly, employees were not deleted yet they link to departments, which no longer exist
