I find it more of an actual problem with hand written notes, since my 9's and a's can look too much alike.
I think the practical problem of knowing what some string, e.g. "23" means is no different than the issue with units. A Mars probe crashed because of a units mismatch; a config file that confused hex with decimal would be the same kind of issue.
