  List some issues, but only earlier version, not BBR3

  BBR1:

  researchers like Geoff Huston and Hock, Bless and Zitterbart found it unfair to other streams and not scalable. Hock et al. also found “some severe inherent issues such as increased queuing delays, unfairness, and massive packet loss” in the BBR implementation of Linux 4.9. Soheil Abbasloo et al. (authors of C2TCP) show that BBRv1 doesn’t perform well in dynamic environments such as cellular networks.

  I believe it will result in like 10% additional overhead, which may be bad on metered connections, but I am not aware of any situation that results in decreased performance. I don’t really know much about this so if anyone would like to correct me, please do.
