This is a big issue as the date that is being used as the cutoff date (1970) is really not that long ago. Many people have birth dates before that date, and so have the potential to be affected.

This is too hypothetical, I'm afraid. People's pre-1970 birthdays are typically recorded as dates, not as POSIX time stamps. (That's true even for post-1970 birthdays.) Although it's conceivable that an application could misuse the data in the way you describe, it'd be pretty weird to do that, and in practice it's not a significant problem. We shouldn't let hypothetical misuse like that get in the way of cleaning out bogus and/or out-of-scope data.
