I tend not to agree with that.

The fact that charset sniffing might happen at the same time as mime-sniffing does not seem like a strong argument to include this in the draft.

Furthermore I would rather have these issues separate:
First you determine the content-type and then after that you may want to determine the charset used within that content-type (if you really have to sniff the charset). I can also imagine that charset sniffing algorithm might be depending on the application identified by the sniffed mime-type, which again would speak against throwing it in together with mime-sniffing....

Kind regards, Tobias

#22: content-type sniffing should include charset sniffing

  the HTML5 spec contains some algorithms for sniffing charset, overriding
  labeled charset, etc.

  MIME parameters like charset are as much a part of the content-type as the
  base internet media type, and any sniffing of parameters and other
  metadata (overriding content-type or guessing where it is not supplied or
  wrong) should be included in this document, since the sniffing will happen
  at the same time.
