Thanks for your suggestion @pc-snatesan! It looks like a nice suggestion for the latest user-event version (we would have to mention that in the docs). A few clarifications:

• The rule name shouldn't contain uppercase, so it should be prefer-user-event-setup
• user-event actually applies to all frameworks supported by this plugin, not just the react one!
