[openssl-project] TLS 1.3 and SNI

Just wanted to check.  The TLS 1.3 draft lists SNI as mandatory to implement, but is not mandatory to use.  Clients should, but do not have to send SNI, and servers may require SNI, but can just use some default chain instead.

Does OpenSSL's TLS 1.3 support mandate SNI in either the client or server?
