I see a few things about full HTML. The issue with that is that it's a security risk, and Wikitext is much more secure, with less ability to insert viruses and other nonsense. CSS is restricted too: you can't even apply some CSS rules to objects in Wikia. due to virus potential. Wikitext is also simpler to use, in general.

Full HTML can be used to an extent using Verbatim tags and custom Mediawiki pages. Yes, you can create any Mediawiki page you want, like "Mediawiki:Whateveriwant", by navigating there and creating the page. Without Verbatim tags, it won't necessarily do anything though.
