this will silence all the complaining in vscode. I can't figure out a nice way to actually turn the errors there into usable errors in yarn lint. Probably need to dig deeper into @typescript-eslint/eslint-plugin.

The alternative to completely ignoring is selectively turning off rules, as some of the remaining rules could be improvements (even if not enforced by our tests). Something like this in .eslintrc.js:

{
  files: ['*.d.ts'],
  rules: {
    'strict': 0,
    'no-unused-vars': 0,
    'no-undef': 0,
    'max-len': 0,
  },
},
