The other impact of closing conenction with an error relates to Alt-Svc. A client maintaining an Alt-Svc cache may interpret a connetion error as a broken service, which could cause a fallback (e.g. to HTTP/2) and a failure to switch to the alternative until the black mark expires. 

We saw _something_ like this between Chrome and Cloudflare, where one of us was mistakenly detecting something as an error. @RyanAtGoogle might recall.
