Indeed there is currently no incremental update in Headway, and deployments are largely an exercise left to the reader.
For maps.earth (a Headway planet deployment), I typically rebuild the world, and then do a blue/green deployment.
I guess the one exception is for transit routing. We have individual transit zones small enough to fit into memory, which can be deployed incrementally. There’s nothing really built in about it - just another level of indirection via our “travelmux” service which redirects your routing queries to a different backend depending on mode and region.
