I don't know - that depends on how you want to define natural=peninsula.
In classic navigation you use landmarks at the coast to plot and verify 
your course.  That is what is meant with the above.

As you can see the concept of 'nearly' is pretty vague here.  The 
description for bays uses the term 'mostly' and look what this has led 


So if you want natural=peninsula to mean something more specific 
than 'some named land area at the coast' (like bay tagging on polygon 
meanwhile just means 'some water area near the coast a mapper wanted to 
label') you better try to make the definition somewhat clearer.
