I’ve mainly noticed it in correspondence when people are trying to sound formal or businesslike. In spoken exchanges, I don’t recall hearing any usage as described in the OP and those particular examples would annoy me because they sound so wrong.
That said, I do agree that people will often say “I’m fine. Yourself?”, and I would not be annoyed by it because it’s so commonplace that I wouldn’t notice or think it was incorrect. I also wouldn’t have a problem with the Kramer example. Now I’m wondering if I commonly make this error myself? Hehe.
