Thanks a lot for all your suggestions, philosophical thoughts and your
patience. :-) I've updated the proposal , particularly the
distinction from natural=cape. natural=peninsula now includes a
minimal area limit of 1 km².
I've also added a recommendation that the length of the non-water part
of the boundary should not be larger than three halves of the square
root of its area. This limit (which is about equivalent to an
equilateral triangle shaped peninsula connected at one of its sides)
is a bit wider than that proposed by Christoph (square root of its
area), thus allowing some peninsulas like Cape Sizun  to be tagged
as natural=peninsula, which otherwise would still lack a tag.
Regarding areas with fuzzy boundaries, i could imagine a new kind of
relation that contains one multipolygon relation for the part of area
that certainly belongs to the area feature ('minimal area') and one
multipolygon relation for the fuzzy area (= 'maximal area' - 'minimal
area'). However, this is not part of this proposal.
