No, BBR does deliver significant performance improvements in high packet loss links. It is designed as a general purpose algorithm (not just for high bandwidth links) - they are using it on the YouTube (and other) content servers as well as between their datacenters. I believe trying to optimise delivery of content to high loss, high latency mobile users was one of the use cases they designed for.
Any window based retransmission protocol just breaks under high error rate, that what happens in wireless links.
