Because, such imperfections can (and most probably will, if the number of games is very high) affect the rating of a program in a way, that it is underrated because it draws "won" games. Some testers, but very few, may look into all such test games and see that a program may be stronger than it's result indicates - But what should they do? The score must not be manipulated, and most often the pure result figures are the main information that is transmitted and consumed. After all, there is a rating list thinking in computer chess. Therefore it is most important, that a program makes the full point from a won game. Otherwise, possible customers are misinformed unavoidably, at least to some degree. So I'm sure programmers are always interested in such info, and it is valuable for them. Btw. there have been cases IIRC where such, or similar, endgames are implanted and tested, but wouldn't work due to certain special unexpected conditions (I remember that a Fidelity computer could solve a tactical? position when it had the original knights from the starting position, but not with knights which were inserted by a board setup, for example.).
