"... a MITM can simply reset the connection until the client retries with SNI."

That doesnt happen when I fetch https://example.com without sending a servername in ClientHello.

For the majority of TLS-enabled websites on the internet, that does not happen. I get the page content just fine witout sending a servername in ClientHello.

But I should send the servername in ClientHello anyway?

This reasoning I am too stupid to understand.
