Good question. This wasn’t discussed but I’m just updating nodes I personally mapped. There are a few issues with canoe=put_in, which is why I started using waterway=access_point as a replacement. Now that this tag has caught on, I’m updating canoe= to be an access tag, which is much more standard and flexible. A boat launch may have different access restrictions for different types of boats, and canoe=put_in can’t specify the canoe access separately. Some mappers have also used put_in to mean you can only launch a boat but not take one out, but I never used it that way so it’s misleading to leave it on.
