Wildcards allow me to serve all of my sub-domains over the same HTTP2 connection rather than causing the client to reconnect/renegotiate TLS/SSL.

This allows me to use domain sharding for those browsers still on HTTP 1.1, yet not have a performance penalty for doing so in the case of HTTP2.

Let's Encrypt does not support wildcard certs but they do support SAN certs, so if your list of subdomains is fixed then you can still benefit from socket reuse with HTTP/2.
