And still, there are things that won't be possible to do, for example
conditional inclusion of resources.
We briefly considered parsing resources on the server, but we
immediately discarded it because it would have killed the server
performance, and it would not have been precise anyway.
That is not to say that WUIC does not have its space, but just that
for Jetty it was not the appropriate solution.
