I had some 'fun' figuring out how to deal with not going through create-react-app without doing a full eject, got something barely working ... and discovered https://craco.js.org/ https://craco.js.org/ already existed and did precisely what I'd part-implemented except better. On the upside, by that point I knew the CRA codebase well enough to predict what it would do even in edge cases, and CRACO's implementation was immediately comprehensible, and none of my colleagues had to try and understand my half-arsed NIH version. (avoiding being in any of this situation in the first place would likely have been preferable, but given where things were when I landed on the project in question that would've required a TARDIS)
