What affects a skin should not necessarily affect the other one. Besides, if some imports are specifically designed to affect the Monobook one, shouldn't it be just placed on top of MediaWiki:Monobook.css file? The @import is for importing different style sheets, fonts, etc. Then we apply what was imported by using certain CSS rules. For example, if Jumosan wanted to only have the font be on the Wikia skin and not the Monobook skin, they would have the @import in Common.css, and have the font-family styling (like what I have offered above) in Wikia.css and not Monobook.css. And vice versa.

Now if they want both to skins to be affected, they put the styling in Common.css or in both Wikia.css and Monobook.css. The @import rule just imports what is wanted to be imported, it doesn't change the looks unless used with a CSS property.
