Yes, that's what I think too, but since many wikis have that, it would appear that that is not the case.

edit: Then again, some wikis still have background images in their wikia header bar, and extra links in their On The Wiki tab, and both of those things are against the customization policy, so it's hard to tell by example sometimes.
