I've made a few bone-headed mistakes in the past that theoretically could be caught by ESLint.
In particular I had issues where classes are being applied but the classes have no content. The reason why is because I was using Panda functions in a file that was not included in the panda.config.ts inclusion glob.
An ESLint plugin could have caught this issue e.g. "hey you're using panda functions in a file that is not included in panda's scanning config, we suggest updating your panda.config.ts".
