AWS Application Load Balancers seem to default to round-robin, would be interested to hear how many people change this to their "least connections" equivalent called "LOR" [1]? And why they don't support any other options?

I'd guess AWS default to round robin because it's the least complex, and doesn't have issues like if a worker responds extremely quickly due to an error (eg. returns a 500 immediately) then using LOR it seems it would consume all the requests until it's taken out of service by any health checks. But maybe there are other potential downsides?
