That's true. Security and convenience are often contraindicated. If you
let people do clever things with IP headers the results can be good or
bad. Personally, I think that having IP addresses as part of your security
is dangerous.

Sure they do. You can bind different plugs to different IP addresses on the
outside.  It's hard to do with plug-gw but my plugdaemon handles it... and
it also has the ability to do round-robin itself.

The skill comes in satisfying the business needs without abandoning any
more security than is necessary.
