The problem is, no one knows. Deep inside some application running an
online banking system is a bit of code that says printf("1.O") where it
should have said printf("1.0"). You issue your erratum, a new release of
a parser is produced to conform to it, and hey presto, the online
banking system goes down and no-one knows why.

This stuff is mission-critical and not to be tampered with so lightly.
