Use 2.0 style parameter help/hints for system Functions?

Can you put back the 2.0 style parameter help/hints for system Functions? E.g. in 2.0 the autocomplete text inserted for the DATEPART is "DATEPART(datepart, date)" but in 3.5 it is only "DATEPART()". If this is controversial can you make 2.0 vs 3.5 behavior for this functionality configurable?
