They make people on the main road slow down, which is a feature, not a bug. What you mean is that they're the most efficient at what they do when the traffic is comparable. They only reduce accident at the expense of a slightly lowered throughput if the traffic is highly disparate.

Right but it's not like a 4 way stop is going to perform better. In the same case you'd expect it to be a 2 way stop.

    A 4 way stop does perform better than a roundabout given highly disparate traffic volumes, because roundabouts suffer from resource starvation in that scenario, but 4 way stops are starvation-free.

    Which is what it was for the first 70yr... And what most of them in this particular neighborhood still are, with a 0-6mo intermission.
