Github user jpeach commented on the issue: https://github.com/apache/trafficserver/pull/864 AFAICT the RFC7232 language was introduced in HTTPbis ticket [#406](https://tools.ietf.org/wg/httpbis/trac/ticket/406). It seems like this change was regarded as a bug fix to RFC2616 rather than a change in requirement or semantics.
