If I was expected to bring my own boat, then what kind of "crossing" would
that be, other than the path ending on one bank and continuing on the
other? We're mapping actual features, so as much peculiar as it would seem,
with "water_crossing=boat" I would definitely expect to find a boat there
(or, more likely, evidence of there once being a boat, long since sunken or
vandalized or stolen).
