Proxy Meteor behind NGINX, good or bad?

Is proxying Meteor behind NGINX a good idea or a bad idea?

I came across this article while researching this topic. I know it’s old, but it made me start to consider doing it for my app. One of the main reasons it states to use NGINX in front of Meteor is because Meteor didn’t support SSL yet. I’m also considering NGINX for 404 pages, because of the problem with Iron Router giving a status code of 200 on 404 pages.

So my questions would be:

  1. How well does Meteor support SSL natively in this latest version?
  2. Is there any other way of reporting a status code of 404 on 404 pages with Meteor?
  3. Would doing a proxy break any functionality with Meteor, such as appcache or anything like that?
