A value of list also indicates that the options in the list are the only 
ones that match what the user has typed thus far.  That is, the more the 
user types, the fewer the options.  If aria-autocomplete is not set to 
"list", then the list will show all possible options and not only matches.

However, I don't have an opinion about deprecating the current 
aria-autocomplete values, mainly because I don't have a feel for if 
users find them useful or not.  A sighted user can see whether the 
completion is inline or not, whether the list is filtered or not, or 
both, or neither.  Is that important to relay to AT users?  I would need 
some form of user studies to be convinced either way, but I don't see 
that happening in the ARIA 1.1 time frame.
