Whoever designed TLS did not expect third parties, so-called "content delivery networks", "cloud providers", etc., wanting to offer hosting to an unlimited number of customers ($$) on a limited pool of IP addresses
Problem of cleartext SNI was solved in 2011, well before "QUIC" existed
ISPs and other networks operators are continuously losing insights into the traffic they carry with each privacy oriented technology improvements and they just don’t want to become commodity providers because they can make billions of dollars selling everything from information to prioritized traffic etc.
