Yeah, I hear you about the "eject" problem for create-react-app. In CRA1, react-app-rewired emerged as a reasonable approach to no-eject config extension, but CRA2's switch to Webpack 4 (itself having moved towards zero-config) broke almost all the rewired plugins. There are solutions in the works (eg babel-plugin-macros), and alt approaches like Neutrino, but timing is tough right now as there isn't a clearly-established and well-lit path for good defaults plus low-maintenance config.
