There is no Go2. Go2 is not a &quot;thing&quot;, it&#x27;s the <i>absence</i> of another thing. It&#x27;s very Zen. Go2 is everything that Go1 cannot be. If Go1 was the universe, Go2 would be everything outside of it - which is nothing. Anytime someone mentions &quot;This needs to wait for Go2&quot;, what they mean is &quot;We can&#x27;t do this now due to the Go1 compatibility promise, so let&#x27;s leave it for the far future, for a day that may never even come, and table this discussion&quot;.
