My intention with "Maximise Throughput" is to support the bulk-transfer applications that TCP is commonly used for today.  In Diffserv terminology, you may consider it equivalent to "Best Effort".

As far as I can see, L4S offers "Maximise Throughput" and "Minimise Latency" services, but not the other two.
