Why is HTTP2 not the default?

It seems like neither the client nor the server use HTTP2 by default. The server example recently got updated to manually allow HTTP2, but the client example still only uses HTTP1.1. Which begs the question why you even need to do this manually in the first place. I feel like either there should be some helper in the HttpsConnector .with_http2() or it should just be the default. I may be misunderstanding something though.

So hyper-rustls doesn't do ALPN by default and hyper-tls doesn't do ALPN at all. I'm so confused.

I just checked and indeed HTTP2 is not used. If you configure the ALPN protocols it uses HTTP2. I'll open a PR for this.
