I've been reading this thread, and I find myself seeing both sides of the argument. I think "Oh, that is so true!" - and then "Yes, but that is true as well!"
I think for me personally it's very subjective whether I "approve" of a skater keeping - or revisiting - an old program or not. But it's not always as simple as whether I liked the program or no. Now, obviously if I
didn't like a program and gritted my teeth through one season, I'm not going to be overjoyed to hear that I'm in for one more season of it.

However, sometimes I don't want to see a program I actually liked repeated eiither.
For example, I've seen people saying things like "Liza should just go back to Sandstorm!" Now, Liza is my Favourite Lady, and Sandstorm is my favourite program of hers. But I still would not like her to go back to it (she's never said anything about doing so, by the way, just for clarification). I think it has been skated as well as it can be skated already - in fact, Euros 2015 is the only performance of her own that she's really been actually satisfied with (she said so in an interview). If she brought it back, and couldn't perform it as well... the contrast would be noticeable, and even more so it would worry me as a fan, that it would be most felt to be so by herself, and the feeling of difference in her then condition and now would do her confidence no good at all.
All this rambling to say, I suppose, that for me it's a case by case scenario, and wholly subjective.
