Er, how? Headers can be used by any applications for their own purposes,
and are by no means all standardized.

Why pick on that header? You'll get a much longer one from

To: 1 a very long introductory phrase for an address <verylong1@verylong>,
    2 a very long introductory phrase for an address <verylong2@verylong>,
    3 a very long introductory phrase for an address <verylong3@verylong>,


... and so ad infinitum - well, for a long time. Even just 100
recipients would make quite a long header.
