Performance issues and angular-eslint schematics defaults

[digeomel]

I spent many days trying to figure out why after following your instructions our big monorepo project took 50+ minutes to lint. In the end, after lots of trials and errors, I managed to bring it down to 2 minutes, following the instructions in https://github.com/angular-eslint/angular-eslint#eslint-configs-and-performance However, I am wonderin, since many devs seems to be facing these performance issues, and assuming the first thing to try would be this, why isn't this already taken care of by the schematics? I mean, why doesn't the builder create a separate tsconfig.eslint.json file with the default setting that you recommend above, and a .eslintrc.json file pointing to that instead of the main tsconfig.json file which seems to be creating the problems? Also, why aren't folders like node_modules, .angular/cache, dist, etc. already included in .eslintignore? I think this would save a lot of time from many developers, and I cannot see why it's not the default.
