I agree, especially as  more and more libraries have records with no items. (Think a catalogue for a website with the URL in 856u for marc21) 
Or all the project Gutenberg records etc. 

The item level item type is there for a reason. I'm all for simplifying the code but just want to make sure people understand it and don't kill features by accident.
