Some programs do not know important information about simple endgames because
the programmers assume that tablebases will help them.

You cannot say the same about opening books because you can get a similiar
position that is going to be out of book so programs have to know to play
without opening book otherwise they may have problems against opponents who try
to get them out of book.
