Per @martinthomson in #495, SNI is currently not required to be used in QUIC, while it is required to be used in HTTP/2.  TLS 1.3 requires SNI to be implemented but apparently does not require it be to used.

This is a proposal to require SNI for QUIC.

The main reason for this is the scarcity of IPv4 addresses.  As long as something is not required, someone will not implement it.  As long as there are enough clients that do not use SNI, virtual service providers will continue to require a large number of IPv4 addresses.  Since IPv4 address conservation is currently a high priority for the Internet, QUIC should strongly encourage (or, better, require) technologies that further this conservation goal.
