Rate Pace To Reduce Packet Loss

"Congestion" isn't a binary state; in fact, a large-enough TCP flow will self-congest its length with most congestion control algorithms.
However, the older rate pace functionality (without rate-pace-max-rate) does what you describe. It uses the first packet loss (i.e. congestion event) to estimate the bandwidth and pace accordingly.
The purpose of rate-pace-max-rate is to avoid nonsense sending rates that exceed the known bottleneck bandwidth. For instance, there is no point in sending at 1Gbps if all of the flows are going over 4G.
