I have a really large chat app with thousands of users and I realized the other day that I accidentally re-render the root component on _every keystroke_. Still, it's not a disaster and I haven't bothered to fix it because no-one notices.

Shouldn't be a big deal if it's properly split into subcomponents and their props don't change with every rerender as well.
