Having spent some time looking at contact tracing app architectures across the world, I realize how conceptually same they are. Mostly variations are in central or decentral handling of data. BLE based. Similar usage protocol. Instead of 50 odd countries, each making tracing app with ~90% similarity, doesn’t it make sense that there is one grand GitHub repo? Each country instantiates their own variant of it, by injecting own config, while contributing to the this repo. Am surprised at the mushrooming effect here.
