As I understand from my reading on this site, extensive testing was done with this recipe, hence we tell you you've broken the warranty if you change anything before the fruit drops.
It was designed for simplicity, and as such it's fairly reliable and predictable, and honestly, if it'll all clear on its own anyway, why bother having to dodge the fruit and rack it again in a couple weeks, when you can just wait a couple weeks and it'll already be clear?
Some yeasts are better than others for lees aging, and Fleischmann's bread yeast seems to be fine for the 8 weeks or so it takes until the fruit drops if you follow the recipe.
During my own experimentations, breaking the warranty and experimenting with it, I've gone at least 6 months on one batch and no off-flavours that I can detect, and the one batch that did taste kind of funky, I'm pretty sure it was the fruit I used, not the yeast...
