With widespread use of serverside scripts/applications, it's important to be able to do more than just serve plain HTML and images. Plugins, modules, whatever, should be available for things like perl and php, and you shouldn't have to dig through a number of config files just to make it work. It would seem a bit silly to have the clean and simple one be so simple it has to say, "I'm sorry, but to do that you'll have to venture into the lair of the mutant octopus."
