We always have to examine what the choices end up being for which parties. If servers end up limiting parallelism, or requiring roundtrips to ramp up parallelism, then clients which want speed (browsers) will be incentivized to simply open up more connections to bypass the low parallelism limit or slow start. Overall, I think it's better to tolerate the minor suboptimality of having servers RST_STREAM streams if they don't want so much parallelism, rather than incentivize browsers to open more connections.
