I just wish CRA would give me a hook to touch the webpack configs. I'm willing to bite the pain of needing to rewrite my custom configs if they move to something else.<p>Simple example: with webpack it's trivial to configure it to load env-specific extensions. You can have foo.js, foo.dev.js, and foo.mock.js and it will import the correct one automatically based on an env variable. It's three lines of code that I use in all my React projects and it's honestly enough to keep me away from CRA.
