Indeed.

I've personally thought for some time that it would be quite nice if  
all you had to do was call an interface to look up a utility (which is  
sort of a multi-adapter of order 0) or to do some kind of adaption, no  
matter how many objects you wanted to adapt. E.g.:

   auth = IAuthentication()                                 # utility
   auth = IAuthentication(default=None)
   langs = IUserPreferredLanguages(request)                 # adapter
   langs = IUserPreferredLanguages(request, default=None)
   view = IBrowserPage((obj, request), name='index')        # named  
multi-adapter

etc.

Personally I would favour such consistency higher than the current  
behaviour, which may have been invented intentionally but still causes  
confusion once in a while.
