Yes, indeed. I was happy to learn that this option was added just recently (we were using
2.2.6 before).

That's a very clever approach. Kudos to you committers for your foresight.

OT, just to add another potential use case...

In our case the pre-condition for the setup was a lot simpler. One of the customers of our
software is a Swiss bank (i.e. high security by definition). Their simple rule is that whenever
an application wants to talk to the out-side world, the web service host at our company in
this case, the request has to go through a very tight validating security proxy (extensive
input/output verification). Even the connection between the application host and the proxy
must use mutual authentication with server- and client-certificate although it's all within
the customer's own secured network infrastructure. Hence, even if the application needed to
talk to various endpoints the requests would have to go through the same proxy.
In our case, the only problem was that the customer uses his own configuration - and implementation
for certain things - for everything related to the actual SSL socket communication. Here the
requirements went even beyond the highly configurable CXF SSL support. It's common practice
within the customer's  IT department to make use of Java's default SSLSocketFactory feature.
