I've been doing that a bit around Canada - initially in order to help with previous coastline 'inversions' but the work I was doing showed me how farcical the initial import could be. The world does not have staircase-like coasts! Tracing over the landsat is boring but one of these therapeutic things in life, and in far-flung places the coastline of alternative map providers is much, much worse. The global 5m-ish coastline that does/will exist in OSM even on its own is a massive public good.
