|   HEADERS
|     + END_STREAM
|     + END_HEADERS
|       :method = GET
|       :scheme = http
|       :path = /.well-known/http-opportunistic
|       host: example.com
|
|   HEADERS
|       :status = 200
|       content-type = application/json
|   DATA
|     + END_STREAM
|   [ "http://www.example.com", "http://example.com" ]

To be consistent,

	host: example.com

should be

	host = example.com


But my question is that should this be

	:authority = example.com

instead?  This is client which generates HTTP/2 
requests directly.

https://tools.ietf.org/html/rfc7540#section-8.1.2.3

|   o  The ":authority" pseudo-header field includes the authority
|      portion of the target URI ([RFC3986], Section 3.2).  The authority
|      MUST NOT include the deprecated "userinfo" subcomponent for "http"
|      or "https" schemed URIs.
|
|      To ensure that the HTTP/1.1 request line can be reproduced
|      accurately, this pseudo-header field MUST be omitted when
|      translating from an HTTP/1.1 request that has a request target in
|      origin or asterisk form (see [RFC7230], Section 5.3).  Clients
|      that generate HTTP/2 requests directly SHOULD use the ":authority"
|      pseudo-header field instead of the Host header field.  An
|      intermediary that converts an HTTP/2 request to HTTP/1.1 MUST
|      create a Host header field if one is not present in a request by
|      copying the value of the ":authority" pseudo-header field.
