It hasn't been maintained for ages, so at some point you'll want to use some new dependency and find out that you can't. And it's very slow, too, if I recall correctly.
Not OP, but we had issues with SASS that made it difficult to upgrade. It didn't like the M1 architecture when trying to upgrade from Node 12 to Node 18, where as swapping it out for Vite just worked. Given CRA is deprecated, it made sense to move away. I followed a guide[0] which covered most of the things I needed to change and the remaining issues just involved following the build errors.
We also saw much-improved build times, which was a welcome change.
