If I remember correctly, we had a lengthy discussion of @martinduke's proposal at one of the early interims. The conclusion was to count ACKs for congestion control, because QUIC ACK frames can become quite large, and therefore should be considered as load on the network. The exception for ACK-only packets is unfortunate, but the only way to not end up in an acknowledgement loop.
