The problem with mapping as coastline is that for using the data you have to take into account the data for the whole world. There is a special program (https://github.com/joto/osmcoastline) which takes everything mapped natural=coastline and tries to fit everything together. This is a somewhat difficult and error-prone process which sometimes breaks. Typical errors are gaps in a coastline or coastlines going the wrong way around. The process has to detect and fix those errors. Every small error can potentially break the coastline for the whole world. Please do not add more (and more difficult cases like lakes on islands in lakes on land) to the data, otherwise this process will get more brittle than it already is.
