Khabib strikes me as one of those guys who is completely one dimensional, but is so damn good at that single dimension, that it doesn't really matter.
No I don't think he can be called one dimension. In addition to his takedowns and sub defense - if his sub defense wasn't up to par Dos Anjos would have caught a limb and ended their fight in a couple minutes - there's the fact that while his striking often looks visually unappealing he has been able to use it effectively to damage opponents and convince judges he's winning the fight. He ain't one dimensional like Palhares.
