I'm not sure the last time the issue was looked at, but I could consolidate some of the benefits that have brought up here:

* Websockets support

* Http/2 support

* Layer 7 routing + Route to specific ports(stop sending all traffic to all nodes and preserve source ip)

* Request tracing(recently added to ALB)

I hope this doesn't sound too negative, and I KNOW you do a TON of work on this stuff, but there often seems a disconnect between the people working on the kubernetes integrations and the feedback coming through from people trying to run businesses on AWS. Which happens; it's tough to be in both roles if your business isn't infrastructure.
