I’m consciously relying on FQ behaviour and the BLUE component of COBALT to take care of flows unresponsive to CE marks. They harm their own latency and don’t get (much) improvement in throughput, FQ keeps them from impacting other flows, and BLUE starts dropping if their window growth is unbounded.
