I thought best practice for HAproxy was to run two HAProxy's in parallel with VRRP or DNS load balancing?
Does that not achieve the same outcome? I've used HAProxy for layer 4 in the past without any issue this way.

To be clear, the HAProxy+vrrp+dns is often a better solution, but this describes an interesting design for a load balancing system that can handle many orders of magnitude more traffic and have maintenance without breaking established connections (one of it's core design features)
