If the recipe isn't great, you'll know and maybe make changes to salvage it. My family has several recipes like that, where the original is "meh", but after tinkering it becomes a staple.
Most notable are our chocolate chip cookies. They started out as Toll House, but now includes browned butter, better chocolate chips and a few other techniques that makes complex tasting cookies.
I struggle with this when I come up against an instruction that my experience tells me is a very bad idea. Especially since I make a lot of recipes from random blogs. I have to determine what weird instructions will result in a cool new experience verses what will ruin a dish because the author is an idiot.
