Haha, yeah, the fewer steps the better, am I right? Although, if we're going for the A+ answer, Option C with ProxyProtocol v2 might be the way to go. Gotta show off those advanced load balancer skills, you know?

Hmm, I'm leaning towards Option A. It just seems like the cleanest and most straightforward way to meet the requirement. Plus, I don't really want to deal with enabling any additional attributes if I don't have to.
