It's not insane if there is no other way to ascertain that information. If it's available through sysfs or debugfs (and, even better, documented as part of the API in Documentation/ABI), then I don't think anyone would object to changing a log message. But I don't think all log messages should be fair game under some general principle if they are being changed (instead of just extending it) without a compelling reason, such as technically being incorrect in its present form.
