So one of the things that is on the cards is to have path based
routing to various ports on the proxy itself. So you can say
metrics.wmflabs.org/hadoop-management go to instance1 port 50070 and
metrics.wmflabs.org/ go to instance1 port 80, etc. Waiting for this
roll out to complete before I get on that :D

Also, adding a new subdomain is completely free - you can just have
hadoopmanagement.wmflabs.org point to management interface, for
example.

So if you are running web services / http on arbitrary ports, you can
still easily use the proxy. It is only public non-http ports that are
a problem.
