Can you please avoid putting the above header lines into your patches?

The only one that may be necessary is the From: line, but that's only
needed if you submit from a different address.

Also please don't send To: mailing lists. Use CC instead. In fact, there
should be *one* address in the To: field when you're submitting a patch:
The address of the maintainer you want to apply the patch for you.

Do you have any examples of when this helped and no other debug methods did?

It seems odd to me that no one has ever asked for this for several years and
now you need it.
