The full stack is the current execution stack (`new Error().stack`) + the current owner stack (`React.captureOwnerStack()`). The idea with the top frame was that when we append it to console.error we'd include both since otherwise the true reason would be obscured behind the little `>` to expand. So we'd just put both stack front and center. By adding this into getCurrentStack it was easy to use the same filtering. I never implemented in Fizz or Flight though. However, with the public API `React.captureOwnerStack()` it's not necessary to include the current stack since you already have it and you'd have filtering capabilities in user space too. Since I'm removing the component stacks from React itself we no longer need this. It's expected that maybe RDT or framework polyfill would include this same technique though.
