Not OP, but one rationale would be that there are replacements for Go. Flutter seems to exist in a space where there aren't a ton of solutions, since I don't think react-native works on desktops (yet? Unless that's changed). If you kill Go, you can use Python or C++ or Java or etc. It might not have the exact paradigm you want, but it'll work. I don't think it's a great justification, though. You could probably add Electron support to react-native for fewer engineer hours than it takes to build and maintain Flutter.
