Unsolicited response received on idle HTTP channel starting with comes from f288526374/src/net/http/transport.go (L2242C16-L2242C80)

Is golang not RFC-compliant?

`Unsolicited response received on idle HTTP channel starting with` comes from https://github.com/golang/go/blob/f2885263748364a2a7f4e0d47abd5095699cd39f/src/net/http/transport.go#L2242C16-L2242C80 Is golang not RFC-compliant?
