I interpret that write-up to mean the daily reboot was a temporary user-suggested workaround for a bug discovered in the field, rather than something in the product specs from the beginning. And it makes more sense to me that no one realized the errors would accumulate or thought to test long operation in general than it would for them to have explicitly said it wasn't important.

Kind of like nobody thought to see what happened if Windows 95 managed to stay up for over 49.7 days [0], only deadlier.
