Except it doesn't work.

It's easy to coax BBR into converging on using 20% of a shared link instead of 50% (cohabiting with one other stream).

The inverse is true and it's easy to get BBR to hog 80% of a link instead of 50% (cohabiting with one other stream). If you're happy for other people to steal bandwidth from you with greedy CCAs then go ahead and ratelimit yourself. I'm not.

It's still useful when dealing with high-latency links with non-zero loss. Fine, something might outcompete it, but without it the throughput would suck anyway.

E.g. if a service runs on a single server (no CDN) and you occasionally get users from Australia then the site will by a bit laggy for them but at least it won't be a trickle.
