Yes agree, there there are a number of "philosophies" on this...
My Last company had "Greyed Out" features in one product, the other product (same company) did not show any unlicensed features...
BTW Actually there are Basic / Free Machine Learning features that is why it is there... Data Vizualizer is an Free / Basic ML Feature which is used to import data or visualize and existing index. You will notice the other features are greyed out.
