At the moment, we state that _a QUIC packet that contains frames other than ACK and PADDING_ ([section 1.2](https://quicwg.org/base-drafts/draft-ietf-quic-transport.html#rfc.section.1.2)), but I wonder if that is true for CONNECTION_CLOSE frame.

A CONNECTION_CLOSE frame never elicits an acknowledgment. IIUC, it is not meant to be governed by the congestion controller.

Considering the aspects, I think we should add CONNECTION_CLOSE to the list of *non-*ACK-eliciting frames.
