No issues so far with prototypebrewery.io, but it's just couple of days since we switched. We don't have massive traffic there and 99.9% is from newest modern browsers. Still, I hope with fallback to HTTP/1.1 we're safe, don't you think?
The HAProxy makes sense only if you need a load balancer in front of several Nginx back-end server. In case of just one instance of Nginx you wouldn't use this configuration. I actually make an amend in the article to make it clear.
Nginx still has setup for HTTPS in the presented configuration. And why not - it doesn't do any damage and has a couple of benefits. You might still want to access Nginx nodes without HAProxy layer, e.g. for monitoring/debugging purposes. Also, if your developers use this setup on their laptops (with Docker images), they can run a smaller stack, without HAProxy, while developing the app. IMO very useful feature.
