I don't understand the benefit ???

This seems like unnecessary overhead for any startup software companies, costing both extra time and money while overloading your server right out the gates.

Instead of expecting 100 requests per min from say like 20 users, I can now expect 1000s+ to my server because I'm sending every keystroke to the server ???

That means I'll need a super expensive instance to handle all those users and this is in the extremely conservative use-case of 20 users at once.

No thanks.
