I worked on IBM selectrics and Wang processors. That was not available. Why would you even do it? Even if you could, you’re only typing out a redundant form?
The reason why people would manually adjust kerning is the same reason why it might have been done on a birth certificate. We used to do it so that we could fit more text into blocks on government forms. If you had an extra character or two that wouldn’t fit using normal kerning, you could scrunch it a bit to make it fit. I’m not saying that’s what was done with the Obama birth certificate, but it’s one plausible explanation.
