title: How to disable eslint rule with create-react-app?
body: <p>If I put <code>EXTEND_ESLINT=false</code> to .env, eslint stops working. It stops warning me about any rules.</p>
  
  <p>I was using craco and everything was fine, then I realised that I want to build my app into single js and single css file. I was unable to do it with ejecting or craco, but it worked with react-app-rewired. And now I switched to react-app-rewired, but can't get eslint working.</p>
  
  <p>I've even created github repository to reproduce it:
