> A ‘boost’ has never been seen.  Bandwidth graphs where there is no packet loss look like:

That's very odd, if true. Westwood+ should still be increasing the congestion window additively after recovering, so even if it got the bandwidth or latency estimates wrong, it should still recover full performance. Not necessarily very quickly, but it should still be visible on a timescale of several seconds.

More likely is that you're conflating cause and effect. The packet is only lost when the boost ends, so if for some reason the boost never ends, the packet is never lost.
