add a "always pure" config for react components

[mh-alahdadian]

Do you want to request a feature or report a bug?
request a feature

What is the current behavior?
as default all the components are behave as impure-component

What is the expected behavior?
I want react to give a config and then I can tell it I'm always write my components as pure components and then I didn't need React.memo before all my components and as you know React.memo will only handle props not state (hooks).

I don't know why default behavior is impure component I had never use them it's so ugly in my mind

Hi 👋 What you're describing would be a large change. This sort of thing is better requested as an RFC:
https://github.com/reactjs/rfcs/

Here is a related RFC:
reactjs/rfcs#108

And here is a related comment from Sebastian that you might be interested in:
reactjs/rfcs#108 (comment)

I'm going to close this issue since this sort of thing belongs in the RFC repo 😄
