I think that Delphi took a bit of a "kitchen sink" approach when compared to classic Pascal, for practical reasons of being most useful to a working programmer, rather than being academic. Specifically the infamous yet influential essay "Why Pascal is Not My Favorite Programming Language" has a laundry list of reasons why academic Pascal is hard to use "for serious programming", and many of them have been corrected in Delphi.
