DSM-5 also forgoes Asperger's and just includes it into autism now, which a _lot_ of people with either diagnosis tend to disagree with. There are many different ways autism and its variations present, and trying to "homogenize" them all into a single narrow label masks the complex nature of the condition (IMO).

There seems to be a ton of debate on lumping and splitting various disorders in the DSM. If I remember correctly academics like to split, practicing clinicians like to lump. There is so much overlap in many conditions that psychologists and psychiatrists that actually deal directly with patients question the need to split every small permutation of symptoms into a distinct disorder. I'm not saying the DSM-5 is absolutely free of issues as I'm sure DSM-6,7,8,20 will be an improvement.
