Repro

Going off the code snippet here: #4124 (comment)

This gives an error [playground link]:

import { TSESLint } from '@typescript-eslint/experimental-utils';

// Generic type 'RuleModule<TMessageIds, TOptions, TRuleListener>' requires between 2 and 3 type arguments.
export const rule: TSESLint.RuleModule = {

Although I personally would use RuleCreator, or failing that specify those TMessageIds and TOptions type arguments, it is inconvenient for folks getting started with writing rules to have to specify them. It would make for smoother documentation if we didn't have to walk people through setting them up until they're needed.

Proposal:

interface RuleModule<
-  TMessageIds extends string,
+  TMessageIds extends string = string,
-  TOptions extends readonly unknown[],
+  TOptions extends readonly unknown[] = [],
