So you are suggesting unpaid overwork, right? I agree that it can be educational, however, it can also give your boss the false pretense that you are gonna do it "outside the sprint". I personally did that mistake in the past, and I have seen people do the same. Never again. Again, the only good thing in that is the learning part and, if you want, the satisfaction. However, you can't even publish it, which means in terms of visibility, nobody knows what you do outside work. And what when they ask you "any side projects?" in job interviews?
