The seals do last an unbelievably long time. I don't always replace them, but good quality seals are cheap, hard to access and can coat a new timing belt with oil if they do fail. So it can be a good idea to replace them when you have access to them. I've seen some that were leaking badly, some that were just barely seeping oil, but most seem to just last forever. I replaced my cam seal and front crank seal when I did my timing belt last time. And I replaced the rear crank seal when I did the clutch. I don't recall any of them leaking, but I was switching to 0w-20 synthetic oil and wanted to make sure my car stayed leak-free.
